What are non-structural safety measures?

Structural and non-structural measures Structural measures are any physical construction to reduce or avoid possible impacts of hazards, or the application of engineering techniques or technology to achieve hazard resistance and resilience in structures or systems.

1. Non-structural measures are measures not involving physical construction which use knowledge, practice or agreement to reduce disaster risks and impacts, in particular through policies and laws, public awareness raising, training and education.
2. Annotation: Common structural measures for disaster risk reduction include dams, flood levies, ocean wave barriers, earthquake-resistant construction and evacuation shelters.

Common non-structural measures include building codes, land-use planning laws and their enforcement, research and assessment, information resources and public awareness programmes. Note that in civil and structural engineering, the term “structural” is used in a more restricted sense to mean just the load-bearing structure, and other parts such as wall cladding and interior fittings are termed “non-structural”.

What is the difference between structural and nonstructural mitigation?

Non-structural mitigation differs most significantly from that of structural mitigation in that it reduces risk (likelihood and consequences) without requiring the use of engineered structures. Nonstructural mitigation techniques are often considered mechanisms where ‘man adapts to nature.’

What is considered non-structural?

Non-structural vs. Structural: The mechanics of deconstruction When you think of demolition, you probably imagine a wrecking ball knocking down a structure in a few hours. Aside from protecting the bulldozer and operator, there’s often no plan and no rhyme or reason to a demolition.

• Deconstruction, on the other hand, takes planning.
• As a licensed and bonded demolition contractor, our has decades of combined experience coming up with and executing these plans for all kinds of deconstruction projects, big and small.
• That means from the roof to the foundation, we can help maximize reusable and recyclable materials yields and divert all kinds of building materials out of the waste stream.

Structural vs. non-structural deconstruction One of the first questions we try to answer when we’re approached about a deconstruction project is whether the work will be non-structural or structural. What we call salvage work is often called non-structural deconstruction, which allows for materials to be removed from a building without compromising the load-bearing or exterior walls and the roof.

Non-structural items include things like doors, cabinet sets, flooring, trim, windows and other finishing materials. In contrast, structural deconstruction requires more integral components of a building, like load-bearing walls, to be systematically dismantled. Usually we take apart a building in the reverse order that it was built in, starting at the roof and working our way down.

Because of the infinite variety in building methods and styles, this structural work requires a greater general knowledge of the industry to plan accordingly. Anticipating and preparing for each step of the process ensures the safety of our crew and prolongs the buildings structural integrity during deconstruction.

• Prior to the 1990’s, structural deconstruction was performed very rarely, and only as a means to reclaim extremely rare or expensive materials, like oversized old growth beams or leaded glass bay windows.
• However, interest in the field has been revitalized in recent years, primarily due to the massive volume of lumber that deconstruction projects can yield.

Decon diaries: the series Deconstruction is more than structural vs. non-structural.This is the part of a multi-post series that will dive into the interesting world of deconstruction. We invite you to follow along. As we add more to this series, : Non-structural vs.

What are the types of non-structural?

Non-structural components can be categorized into architectural, mechanical and electrical components. This paper will present a bow-tie based earthquake risk assessment analysis for mechanical and electrical

What are the four types of non building structures?

Examples of nonbuilding structures that are not similar to buildings include earth-retaining structures, tanks and vessels, telecommunication towers, stacks and chimneys.

What is an example of a non-structural element for a building?

10 years have passed since the magnitude 7.1 Darfield earthquake shook the ground beneath Canterbury, kicking off what has been a decade of significant earthquake activity in New Zealand. Non-structural seismic specialist Dr Andrew Baird reflects on the growing importance of ensuring non-structural elements are considered in earthquakes, given his first hand experience.

– When the 2010 Darfield earthquake struck, I had just started a postgrad research project at the University of Canterbury, looking at ways to reduce earthquake damage to non-structural elements in buildings. The experiments I had planned in the university lab that summer were intended to replicate earthquake damage to buildings.

The quake itself closed the lab and my tests were scuppered. Instead, laid out across the city of Christchurch were thousands of real-world examples of earthquake damage to learn from. Unbeknown to me at the time, the Darfield quake would shape my career.

It would lead me to obtain a PhD in earthquake engineering in 2014, and to working as a consulting engineer for Beca, where I’ve spent much of my time improving the seismic performance of non-structural elements in buildings – so we don’t see as much damage next time there’s a decent shake. What are non-structural elements? Over the past decade, there has been a shift in the way that engineers approach the design of a building.

The damage to buildings that occurred in Christchurch and later in Wellington during the 2016 Kaikoura earthquake, highlighted that getting a structure through an earthquake is not enough. It is also necessary to get a building’s fitout, fabric and contents through the earthquake too.

• Such items are often grouped together in what we call ‘non-structural elements’ – these are all the parts of a building that are essential to its functioning, but are not there to hold the building up; such as ceilings, partitions, HVAC systems, electrical systems, plumbing and drainage etc.
• Why do we care about non-structural elements? Non-structural elements comprise up to 70% of a building’s capital value.

It’s not surprising then that the damage to these elements in an earthquake has resulted in many buildings being declared economic losses, even when the structure itself was not badly damaged. Damage to non-structural elements also presents a significant risk to building occupants and affects whether the building can be reoccupied following an earthquake.

Non-structural element damage is the main contributor to overall NZ earthquake injuries Non-structural element damage is the main contributor to building related property loss and business disruption following an earthquake

What can we do to improve? You might assume that the poor performance of non-structural elements in recent earthquakes points to shortcomings in the building code and design standards. While improvements to the design standards are necessary to bring them up to date and make them easier to implement, the biggest hurdle remains having appropriate seismic design undertaken and this design being properly implemented.

A survey conducted in 2016 for MBIE found that typically between 50-80% of ceilings, partitions and services are inadequately braced in commercial buildings. The design of seismic restraints for non-structural elements lies at a messy junction between structural engineers, building services engineers, architects and contractors.

Experience has taught us that unless someone takes responsibility for the design and coordination of the seismic restraints, it will likely fall through the cracks. The role of a specialist seismic restraint designer is now emerging in New Zealand. This specialist role has existed in the United States for many years, after they went through a similar learning curve following the devastating 1994 Northridge earthquake.

The role is effectively an entirely new discipline combining structural, building services and architectural knowledge and experience. The multi-disciplinary demands on this role make it more suited to a multi-disciplinary team of specialists who can collaborate and develop solutions that achieve the seismic restraint requirements, while not compromising the functionality of the element being restrained.

For example, the seismic restraint design of a pipe requires a structural engineer to design for the seismic demands upon the pipe, but also requires input from an industrial engineer to understand the pipe’s thermal expansion and contraction demands, as well as any thrust force considerations.

1. A better way Part of the solution involves getting a seat at the design table earlier.
2. Historically the design of seismic restraints was not undertaken until the construction phase of a project.
3. This led to poor design outcomes, poor cost-certainty and very little opportunity to coordinate the seismic restraint requirements of different disciplines.

If seismic restraint design is undertaken earlier in the design programme, the approach can be coordinated between disciplines. This improves construction efficiency and also ensures a compliant design is completed and adequately costed. However, early design is not without its challenges.

1. Unlike traditional building services and structural engineering disciplines, seismic restraint does not naturally lend itself to hand over from Designer to Contractor at the end of the design process.
2. This is because many seismic restraint design outputs are dependent upon the Contractor’s final equipment selections, as well as construction phase set out and coordination.

It is therefore essential that an early design procurement model includes continued input between Designer and Contractor. The final piece that has enabled a step change in the approach to seismic restraint is the advancement of 3D BIM modelling tools.

• Modelling of seismic restraints at the same time as other disciplines means that coordination can take place easily during design.
• This is essential for complex buildings like hospitals and laboratories, to ensure that buildable solutions are achieved.
• With these tools, the lessons learnt from recent quakes and the knowledge of what has been successful in the United States, there is no reason why we can’t build better buildings.

What are three examples of non-structural mitigation?

Non-structural measures in the ‘mitigation’ category include ‘ building a cooperative and coordinated system,’ ‘raising awareness of disaster preparedness,’ ‘citizen participation’ and ‘stable financial support’.

What are some examples of structural hazard?

Structural hazards – A structural hazard occurs when two (or more) instructions that are already in pipeline need the same resource. The result is that instruction must be executed in series rather than parallel for a portion of pipeline. Structural hazards are sometime referred to as resource hazards.

What is structural and nonstructural problem?

Structural and non-structural measures Structural measures: Any physical construction to reduce or avoid possible impacts of hazards, or application of engineering techniques to achieve hazard-resistance and resilience in structures or systems; Non-structural measures: Any measure not involving physical construction

Hint: Structural mitigation steps are those that include or dictate a need for some form of design, engineering, or other mechanical modifications or enhancements aimed at mitigating the probability or effect of a hazard risk. Complete answer: So, the correct answer is Option E. Note: It is important to remember that these forms of mitigation are similarly important, and in conjunction with each other are better used. Education regarding local dangers and practising a strategy is as critical as providing a concrete shield of protection from such risks like a storm shelter or a strengthened base of a house in an earthquake

Mitigation involves reducing the effects of catastrophes. Structural mitigation and non-structural mitigation are two types of mitigation. The prevention that is performed in either a structural or a non-structural context can require emergency response.

• Structural Mitigation is the physical alteration or act of accident or danger security.
• Structural mitigation, for example, will be where a family improves its house to make it more windproof or earthquake proof.
• In comparison, where a flood would arise, such structural mitigation examples might be items such as building a sandbag barrier around the house.

In general structural mitigation is the direct acts that people take, create, or transfer in order to help protect their life and or property.In disaster response, non-structural mitigation involves what people should do at a personal level that is not structurally or externally visible as a defensive defence such as a surge wall or storm shelter.

In general, non-structural mitigation would include measures such as flood insurance. In comparison, a family having a family emergency plan would be another example.Dams, flood levees, ocean surge walls, earthquake-resistant construction and emergency shelters are common structural steps for disaster risk mitigation.

Construction regulations, land-use planning legislation and their implementation, study and appraisal, information services and public awareness programmes are common non-structural steps. Notice that the word “structural” is used in civil and structural engineering in a more narrow way to mean only the load-bearing frame, and other elements such as wall cladding and internal fittings are considered “non-structural.”prone area.

What are non-structural defects in buildings?

What are non-structural defects examples? – Some examples of non-structural defects include (a) dents in the walls or finishes; (b) general deterioration of the works; (c) minor corrosion with the works; (d) spalling and degradation of concrete; (e) small blemishes to the works; (f) failing gutters and roof coverings; (g) thin cracks or minor settling-in cracks; and/or (h) uneven finishes and non-level finishes.

What are non-structural repairs?

Non-Structural Repair means work undertaken to restore the damaged interior and exterior parts of a Motor Vehicle, that do not have an intrinsic bearing on the mechanical functioning of the Motor Vehicle, including plastic, aluminium, and steel parts.

What is the difference between structural and non-structural improvements?

A non-structural remodel is just that It is a project that does not necessarily involve altering the structure of the house. In terms of structure, we are talking about walls, windows, the roof, and anything that is integral to keeping that structure together.

1. If you move a wall, generally this will be structural.
2. Redoing a portion of the roofline is also considered a structural project.
3. With a non-structural remodel, you are usually focused on more cosmetic changes.
4. Changing the plumbing fixtures for example would be a non-structural remodel.
5. Putting in new flooring is also another example of this kind of home improvement project.

Below are some of the benefits of doing a non-structural renovation project in your home.

It has the potential to increase your home’s value, Now granted, the biggest ROI usually will come from those larger projects, and often this might mean structural renovation projects. However, even non-structural remodel projects can add a great deal to a home’s value. For example, let’s say you renovate your kitchen and replace the cabinets and countertops. You’ve not only modernized the space and made it more aesthetically pleasing for you, but now you have made it far more attractive to a potential buyer down the road.

You can make your house more energy-efficient and thereby reduce utility costs, There are a number of non-structural home improvement projects that will help you to optimize your home’s energy efficiency. Especially if you live in an older home, you might be losing more money than you thought because of high energy bills. A home renovation project is one way to address that problem.

A home renovation makes your home better for you, Be it a structural or a non-structural remodel job, the end result is usually one in which you as the homeowner are happier with your space. Isn’t that what your home is all about Being happy, relaxing, and enjoying your house during the moments when you get to be in it.

What are the two classifications of non building structures?

Conclusion – This article has provided an introduction to the seismic design of nonbuilding structures to ASCE 7-16. Although there are some exceptions as noted above, most of the core concepts used in the seismic design of buildings apply to nonbuilding structures as well. Key takeaways from this article are:

Nonbuilding structures are divided into two different categories for seismic design – similar to buildings and not similar to buildings, Nonbuilding structures are treated differently than buildings in seismic design because of the lack of human occupancy and because nonbuilding structures do not incorporate elements that increase damping and ductility (floors, diaphragms, non-structural elements) typically found in buildings. The presence of liquid in many nonbuilding structures requires the modification of the ground motions used for design. The trade-off between ductility and strength is unique to the seismic design of nonbuilding structures similar to buildings, Many nonbuilding structures rely on the use of Reference Documents for their seismic design.

A follow-up article will cover advanced topics in ASCE 7-16 seismic design of nonbuilding structures and nonstructural components.▪ : Seismic Design of Nonbuilding Structures

What are the 3 basic structural forms?

Universal Principles of Design, Revised and Updated There are three ways to organize materials to support a load or to contain and protect something: mass structures, frame structures, and shell structures. Structures are assemblages of elements used to support a load or contain and protect things.

1. In many cases, the structure supports only itself (i.e., the load is the weight of the materials), and in other cases the structure supports itself and additional loads (e.g., a crane).
2. Whether creating a museum exhibit, large sculpture, 3-D billboard, or temporary shelter, a basic understanding of structure is essential to successful design.

There are three basic types of structures: mass structures, frame structures, and shell structures. Mass structures consist of materials that, : Universal Principles of Design, Revised and Updated

What is non structural design?

Non-structural elements are those which are attached to or. housed in a building or building system, but are not part of. the main load-resisting structural system of the building.

What are structural and non-structural flood measures?

Last Updated on Thu, 01 Jun 2023 | Hydrology Adjustments to floods can be broadly classified into structural and nonstructural measures. Nonstructural approaches involve adjustment to human activity to accommodate the flood hazard (White, 1964; James, 1975; White, 1974) whereas structural methods are based on flood abatement or the protection of human settlement and activities against the ravages of inundation.

Structural change involves modification to the built environment to minimize or eliminate flood damage directly or flood channel construction changes. For example, see Figure 5. Structural measures are expensive. They may give the illusion of security but the record shows otherwise (Alexander, 1993). The security can be temporary.

A flood can occur that is bigger than the design of the channel or levee, and changing priorities in flood control projects that require higher reservoir levels for recreation or water supply can diminish the efficacy of structural measures (Williams, 1998).

• The failure of structural flood control works poses a significant threat to the lives of the people who live downstream from a massive structural project such as a dam.
• More than 2000 people died in 1969 in Italy when the Vaiont Dam collapsed (Blaikie et al., 1994).
• Because of stringent engineering standards and a system of inspections, the United States has seen few major failures.

However, many structures are at the end of their design lives of 50, 75, or 100 years. Structural flood control is still the dominant idea in many parts of the world. Following the 1927 Mississippi River floods, when river levees collapsed and 200 people died, 700,000 were displaced, and more than 135,000 buildings were damaged (Moore and Moore, 1989), the Army Corps of Engineers did not abandon its dream of controlling all floods.

1. Rather, it proposed building large dams upstream to reduce flood peaks to the capacity of the floodway between the levees (Williams, 1998).
2. Until the 1970s, most flood loss reduction efforts involved structural solutions.
3. Although nonstructural measures were discussed as alternatives, they were rarely implemented.

The shift from mostly structural to mixed structural/nonstructural Figure 5 Elevated home in West Virginia is a mitigation success story. Risk is greatly reduced to homes elevated before a flood. See ftp site for color image. measures began in the 1970s and continues today. The mix of adjustments varies for cach situation, in Europe almost all measures that are taken have elements of combined structural and nonstructural measures.

There has also been a move to be antistructural. Some dikes are being removed in favor of nonstructural or more environmentally sensitive techniques (Smith and Ward, 1998). Nonstructural measures include floodproofing, land-use planning, soil bioengineering, warning systems, preflood mitigation efforts, and insurance.

The simplest nonstructural measure is to acccpt the loss. Another nonstructural measure is to provide postflood relief. Protection of lloodplain residents and users, and the supply of relief when they suffer damage, are forms of hidden subsidy (Alexander, 1993).

What are non-structural components in construction?

Abstract – For the majority of buildings, the nonstructural components represent a high percentage of the total capital investment. Failure of these components in an earthquake can disrupt the function of a building as surely as structural damage, and can pose a significant safety risk to building occupants as well.

Past earthquakes have dramatically illustrated the vulnerabilities of the nonstructural components. Apart from the falling hazard posed by the light fixtures, non-structural failures can create debris that can block egress from the building, and hamper rescue efforts. In this Chapter, we deal chiefly with those components and systems that are installed in the structure during construction or remodel, for which design details are provided on the construction documents.

We will touch briefly on the contents and equipment items that the owner or occupants may place in the building. The failure of these items may pose a significant risk to the occupants of the structure. However, these items are diverse, and the designer should address their anchorage and bracing on a case-by-case basis.

Nonstructural elements can generally be divided into architectural, mechanical, and electrical systems and components. Architectural components include items such as exterior curtain walls and cladding, non-load bearing partitions, ceiling systems, and ornaments such as marquees and signs. Mechanical components and systems include boilers, fans, air conditioning equipment, elevators and escalators, tanks and pumps, as well as distributed systems such as HVAC (Heating, Ventilation, and Air Conditioning) ductwork and piping systems.

Electrical components include transformers, panels, switchgear, conduit, and cable tray systems. Components may be mounted at grade (on the ground floor or basement of a building) or installed on the upper levels or roof of the structure. Our focus is on “nonstructural components” as opposed to “nonbuilding structures”.
