PEB Structures​

PRE-ENGINEERED BUILDINGS

The Pre-engineered building system is one of the fast growing segments globally. It has all the attributes of what the modern life-style demands, i.e., speed, quality and value. Pre-Engineered buildings are easy to build, delivered and erect anywhere with low rise structures like canopies, warehouses etc. There are many applications for pre-engineered buildings, it can be automobile garage to aircraft hangar, bakery to dairy farm, auditorium to hospital and factory to community hall. This concept has many advantages over the conventional steel building (CSB) concept of building with roof truss. The study is achieved by designing a typical frame of a proposal Industrial Warehouse building using both concepts and analysing the designed frames using structural analysis and design software STAAD.Pro.

Major components

Primary Framing:

Primary Framing consists of columns and rafters with tapered web and variable flanges. These are manufactured by welding together the cut plates to form the desired frame I-sections. The tapered sections are welded at factory/bolted at site to form the desired frame profile.These frames in PEB are normally moment resistant frames with fixed or pinned bases as mandated by the design.

Secondary framing members:

Secondary framing members are purlins and grits made of cold formed sheets. Normally, secondary framing members are in Z or C shapes. Purlins which are used to support roof sheeting and the grits at longitudinal walls are normally designed as continuous members. However, the grits at transverse or short walls are normally designed as simply supported beams. The spacing of secondary framing members are primarily dictated by the capacity of the cladding to span in between the purlins/grit.

Cladding:

Cladding comes in a variety of profiles which are customized to suit structural and aesthetic requirements.

Benefits

PEB can be constructed in much less than the normal time from other structures.

PEB is a structural concept whereby all the components of a building are designed, detailed and fabricated to suit the specific requirement of design and serviceability.

There would be absolutely no cutting or welding at site.

The erector would only use spanners to connect the various elements together.

Structural Profiles in PEB

Below Figure shows some of the typical frames used in PEB. The various profiles for the primary members are chosen based on the requirement in terms of the building usage, loads, economy etc. The chosen profiles are spaced at distance varying from 6 to 10m in order to form the length of the building. Quite often in buildings a combination of all the profiles indicated are used. This gives lot of flexibility for the building configuration.

CONVENTIONAL BUILDING STRUCTURES

The Conventional building system is one of the oldest standard in Manufacturing Steel Buildings globally. It has all the attributes of what the modern life-style demands, i.e., speed, quality and value. The concept includes the technique of providing the best possible section such as ISMB, ISMC, ISMA, Hollow Pipes, Roofing & Cladding Sheets according to the optimum requirement. It can be automobile garage to aircraft hangar, bakery to dairy farm, auditorium to hospital and factory to community hall.

Benefits

CBS can be constructed in much less than the normal time from other structures using standard ready sections.

CBS is a structural concept whereby all the components of a building are Readily available, fabricated to suit the specific requirement of design and serviceability.

Customization in design or details can be done at site with cutting or welding.

The erector would only use spanners to connect the various elements together.
