Prefabrication though new age, is no longer an ancient concept. Off-site construction has been gaining buzz over the past few years because it is quick to build and also economical. This mode of construction is also eco-friendly, which is not a luxury, but a need in this day and age when the whole world is facing global warming. The time factor is the one that has propelled the popularity of prefabricated structures, which is why it is widely used in commercial and industrial sectors. Once the components are readied in the factory, it is transported to the site for assembling and installation.
Pre-engineered steel structures have a better strength-to-weight ratio than conventional RCC structures. It can be easily dismantled and relocated to another place for reuse. So prefabricated industrial structures have several benefits.
We have illustrated the process and components of pre-engineered structures below:
1. Primary Framing Syestem
Primary frames are structural components that carry the majority of the load and transfer them to the foundation. These consist of beams, columns and are put together by anchor bolts, joists, etc.
2. Secondary Framing system
Secondary frames are those structural components that provide support to the primary framing system. It costs of purlins, eave struts, girts, clips, etc. Secondary frames also provide support to wall and roof structures, besides the primary frame.
3. Analysis and Design of PEB
The process of prefabrication starts with engineers determining the structure through a drawing. The loads, framework, etc are pre-determined with the design of the building happening simultaneously. This ensures precision in design and construction. Industry-leading design software like Autocad or Staad Pro is used for analysing axial forces, bending, beam/column stress, etc. Multiple engineers working simultaneously saves time.
Some applications of Prefabricated steel buildings
Prefabricated steel buildings have multiple advantages. Some of the most commonly found are:
- Industrial Buildings
- Commercial Complexes – Malls, cineplexes
- Site offices
- Sports Stadiums – Indoor
- Parking spaces
Industrial steel buildings are prefabricated cost-effective alternatives to conventional structures. They are durable, offer the flexibility of expansion and are recyclable. Steel is inherently recyclable, which renders these structures eco-friendliness. These structures are therefore sustainable in the long run as it does not deplete the environment.
