Why PEB

Components Of PEB

Technological improvement over the past year has contributed immensely to the enhancement of quality of life through various new products and services. The pre-engineered building was one such revolution.Although its roots can be traced back to the 1960s, its true potential has only recently been realized.This was mainly due to the development of technology, which helped in computerizing the design.

Though initially only off-the-shelf products were available in these configurations, aided by technological development, tailor-made solutions are now also made using this technology in very short durations. A recent survey by the Metal Building Association (MBMA) shows that about 60% of the non-residential low-rise buildings in the USA are pre-engineered buildings.

Although PEB systems are extensively used in industrial and many other non-residential constructions worldwide, they are a relatively new concept in India. These concepts were introduced to the Indian market in the late 1990s, with the opening up of the economy and a number of multinationals setting up their projects.

Pre-engineered buildings are the most cost-effective and time-efficient construction units because they use a predetermined raw material that has been proven over time to satisfy a wide range of structural systems with creative designs.

A pre-engineered steel building is a building shell employing distinct product categories.

  • Built-up "I" section to build primary structural framing members (columns and rafters).
  • Cold-formed "Z" and "C" sections to form secondary structural members (roof purlins, eaves, and wall girts).
  • Roll-formed profiled sheeting (roof and wall panels)
  • Optional subsystems, which include mezzanine floors, custom beams and rafters, crane runway beams, roof platforms, catwalks, etc.
  • Custom beams and rafters for unique frames to accommodate the large openings and clear access for ease of operations, which include portal frames, high-level mezzanines, 2nd floors, fascia, soffits, and other applications

Nomenclature

A plan view of a building's foundations displaying all dimensions and sections needed to locate the anchor bolts, such as the bolt projections above the concrete surface, the required recess, and so on.Column reactions (magnitude and direction) and base plate dimensions are also included.
Bolts are used to anchor structural members to a concrete floor, foundation, or other support. usually refers to the bolts at the bottom of all columns and door jambs.
Drawings sent to the customer to verify design and dimensions, as well as the sales contract description of materials and services agreed to be provided by the manufacturer.
The space between the center lines of frames or primary supporting structures in the longitudinal direction of the building. (This is also known as bay spacing or bay length.)
Rods or cables are placed diagonally in the roof and walls for the purpose of transferring wind loads to the foundation and longitudinally stabilizing the building.
The lateral width of the building is measured from the outside to the outside of the sidewall steel lines.
An overhanging or projecting roof structure, below the eave level, supported at one end only.
A cold formed sheet metal section is used to carry water from the gutter of a building to the ground or storm drainage system.
The vertical dimension is measured from the finished floor level to the top of the eave strut.
A line along the side wall is formed by the intersection of the inside faces or planes of the roof and the sidewall panels.
drawings and erection instructions that identify all the individual components in sufficient detail to permit the proper assembly of all parts of the metal building system furnished by the seller.
The onsite assembly of prefabricated components to form the complete structure
An accessory whose function is to enhance the appearance of a wall and is also used to cover the eave or gable of a building
A sheet metal closure used to keep a structure weathertight.
There are primary and secondary members (columns, rafters, girts, purling, brace cables, etc.) that, when connected together, make up the skeleton of a structure to which the covering can be fastened.
Secondary horizontal member attached to the main frame columns. Girts normally support wall panels. It can be a z-section or a c-section.
Rainwater is collected using a preformed light-gauge metal channel installed on the roof, along the side walls, or in the valleys of multi gabled roofs.
A wall opening with slanted blades, either fixed or movable, that allows air to flow inside the building.
An intermediate floor is the floor of a building above the ground floor that occupies all or part of the building floor area and consists of columns, beams, joists, deck panels, and edge trims to receive reinforced concrete.
A piece of roof or wall sheeting.
A horizontal secondary structural member, bolted to the rafters, which transfers the roof loads from the roof covering to the primary frames. The majority of this is the Z section.
A structural frame consisting of members joined together with rigid (or moment) connections so as to render the frame stable with respect to imposed loads without the need for bracing in its plane
The ventilator is used at the ridge line. Roll-up Shutter: A door that opens vertically, is supported on a shaft or drum, and runs along vertical tracks.
A door that opens vertically, is supported on a shaft or drum, and runs along vertical tracks.
An extension of the roof beyond the end wall and/or sidewall of a building Roof Monitor: A raised gable, or portion of the main building, located at the ridge, to allow lighting and ventilation.
Raised gable, or portion of the main building, located at the ridge, to allow lighting and ventilation.
A tension member is used to limit the movement of a girt or purling in the direction of its weak axis before the installation of sheeting.
The exterior cover for a building is generally made of light-gauge metal that has been cold- formed into a configuration having appearance, weatherproofing, and structural qualities.
A translucent panel on the roof or wall to transmit natural light. It is usually made of fiberglass.
A single or double leaf door that opens horizontally by means of overhead trolleys or bottom wheels.
In pre-engineering, building distance between interior columns
A vertical member supporting a wall system designed to withstand horizontal wind loads is usually at the ends of walls.
