This immense strength is of great advantage to buildings. The other important feature of steel framing is its flexibility. It can bend without cracking, which is another great advantage, as a steel building can flex when it is pushed to one side by say, wind, or an earthquake. The third characteristic of steel is its plasticity or ductility. This means that when subjected to great force, it will not suddenly crack like glass, but slowly bend out of shape. Failure in steel frames is not sudden - a steel structure rarely collapses.
Steel in most cases performs far better in earthquake than most other materials because of these properties. However one important property of steel is that it quickly loses its strength in a fire. At degrees celsius degrees F , mild steel can lose almost half its strength. There are several types of steel building construction.
Steel construction is also called s teel fabrication. Conventional Steel Fabrication is when teams of steel fabricators cut members of steel to the correct lengths, and then weld them together to make the final structure. This can be done entirely at the construction site, which is labour-intensive, or partially in a workshop, to provide better working conditions and reduce time.
Bolted Steel Construction occurs when steel fabricators produce finished and painted steel components, which are then shipped to the site and simply bolted in place. This is the preferred method of steel construction, as the bulk of the fabrication can be done in workshops, with the right machinery, lighting, and work conditions.
The size of the components are governed by the size of the truck or trailer they are shipped in, usually with a max length of 6m 20ft for normal trucks or 12m 40ft for long trailers. Since the only work to be done at site is lifting the steel members into place with cranes and bolting, the work at site is tremendously fast. Pre-engineered buildings are an example of bolted steel construction that is designed, fabricated, shipped and erected by one company to the owner.
Light Gauge Steel Construction is a type of construction that is common for residential and small buildings in North America and parts of Europe. This is similar to wood framed construction , except that light gauge steel members are used in place of wood two-by-fours. Light gauge steel is steel that is in the form of thin mm sheets of steel that have been bent into shape to form C-sections or Z-sections.
Consider a single storey building measuring 5 x 8m 16 x 26ft. Let us first construct this in concrete, with four columns at the corners, beams spanning between the columns, and a mm 6" thick concrete slab at the top. The steel framed building will weigh only 2. So the concrete building is over 12 times heavier! This is for single storey structures - in multi-storey structures, the difference will be less, as the floors in multi-storey steel buildings are built of concrete slabs for economy - but the difference is still significant.
This low weight of steel frame buildings means that they have to be firmly bolted to the foundations to resist wind forces, else they could be blown away like deck umbrellas! Steel structures have the following advantages: They are super-quick to build at site, as a lot of work can be pre-fabbed at the factory. They are flexible , which makes them very good at resisting dynamic changing forces such as wind or earthquake forces. A wide range of ready-made structural sections are available, such as I, C, and angle sections They can be made to take any kind of shape , and clad with any type of material A wide range of joining methods is available, such as bolting, welding, and riveting.
Steel structures have the following disadvantages: They lose strength at high temperatures, and are susceptible to fire. They are prone to corrosion in humid or marine environments.

Structural Steel Fabrication. Steel frame construction is steadily increasing its market share in the construction and civil engineering sector. However, is steel framing an effective construction method compared to the alternatives? In this article we will weigh out the pros and cons of structural steel frame construction as a guide for developers and design engineers exploring different construction options. Steel frame construction used to be primarily used for large, simple structures, such as garages, large agricultural buildings and warehouses — as well as high-rise buildings. This is how steel frame construction is still understood in popular belief, but it is now also used for a wide range of other types of development, including offices, factories, schools, public buildings and some residential dwellings. Steel frame construction is a good option for a diversity of projects for many reasons, including:.

The PEB system is the intelligent solution for organisations desiring to deliver large scale production and projects. Flexible, reliable commercial storage and warehousing needs to be built rapidly and affordably to respond to growth. Can be considered one of the most daring buildings in LGS executed in Brazil until today, this construction was challenging. Another success story and an example of innovation and sustainability, as after dismantling of the structure, we reassemble it in another location can be used for commercial rooms. As experts in cold formed steel CFS construction, FrameTech knew exactly which method they would use to bring that space to life. Read this case study to learn how did their award-winning CFS facility come to fruition?
The dominance of steel in the multi-storey commercial sector is based on tangible client-related benefits including the ability to provide column free floor spans , efficient circulation space, integration of building services , and the influence of the site and local access conditions on the construction process. For inner city projects, speed of construction and minimum storage of materials on-site require a high level of pre-fabrication , which steel-framed systems can provide. There is a strong demand for high quality office space, especially in city centres. Corporate headquarters for banks and other high profile companies require that buildings are built to high architectural and environmental standards. In many large commercial buildings, a two stage construction process means that the tenant is responsible for the servicing and fit-out, and so the building structure has to be sufficiently flexible to cope with these differing requirements.
Advantages of Steel
In structural engineering , a pre-engineered building PEB is designed by a PEB supplier or PEB manufacturer, to be fabricated using best suited inventory of raw materials available from all sources and manufacturing methods that can efficiently satisfy a wide range of structural and aesthetic design requirements. Within some geographic industry sectors these buildings are also called pre-engineered metal buildings PEMB or, as is becoming increasingly common due to the reduced amount of pre-engineering involved in custom computer-aided designs, simply engineered metal buildings EMB. During the s, standardized engineering designs for buildings were first marketed as PEBs.
Metal Building Accessory A building product that supplements a basic solid panel building such as a door, window, skylight, ventilator, etc. Agricultural Building A structure designed and constructed to house farm implements, hay, grain, poultry, livestock or other horticultural products.

It is written with the conviction that by focusing on the process of choice, the range of theory and knowledge that is useful to practice becomes explicit, making the link between knowledge and practice, and between understanding and experience. The new edition has been updated throughout with extensive additions to Chapter Manufacture and Assembly and to Chapter S ustainability. An entire new section has been added, covering all the main elements of commercial construction. Students will find here explanations of how environments, structural behaviour, production know-how, cost and social concerns such as sustainability can be taken into account in the choice of construction. They will also gain a clear understanding of the construction details and specifications adopted for both housing and commercial buildings in the UK at the beginning of the 21st century.
Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out. The term prefabrication also applies to the manufacturing of things other than structures at a fixed site. It is frequently used when fabrication of a section of a machine or any movable structure is shifted from the main manufacturing site to another location, and the section is supplied assembled and ready to fit. It is not generally used to refer to electrical or electronic components of a machine, or mechanical parts such as pumps, gearboxes and compressors which are usually supplied as separate items, but to sections of the body of the machine which in the past were fabricated with the whole machine. Prefabricated parts of the body of the machine may be called 'sub-assemblies' to distinguish them from the other components. An example from house-building illustrates the process of prefabrication.
All other materials are measured against the standard of structural steel and structural steel is still the material of choice. These benefits include:. Structural steel enhances construction productivity because of its shop fabrication while maintaining tight construction tolerances. Field placed material will always lag behind
