Pre-engineered buildings are defined by the following basic parameters: Building Length, Height, Width, Roof Slope, End Bay Length, Interior Bay Length and Design Loads.

A. Building Length

Building length is the distance between the outside flanges of end wall columns in opposite end walls. It is a combination of several bay lengths.

B. Building Height

Building height is the eave height, which is usually the distance from the bottom of the main frame column base plate to the top outer point of the eave strut. When columns are recessed or elevated from the finished floor, eave height is the distance from the finished floor level to the top of the eave strut.

C. Building Width

No matter what primary framing system is used, the building width is defined as the distance from outside of eave strut of one sidewall to outside of eave strut of the opposite sidewall.

D. Roof Slope (x/10)

This is the angle of the roof with respect to the horizontal. Generally roof slopes should not be less than 0.5/10. Any practical roof slope is possible.

E. End Bay Length

This is the distance from the outside of the outer flange of end wall columns to the center line of the first interior frame column.

F. Interior Bay Length

This is the distance between the center lines of two adjacent interior main frame columns. The most common bay lengths are 6, 7.5, and 9 meters. Any bay length is possible up to 15 meters.

Design Loads

Unless otherwise specified, Vibgyor’s Pre-Engineered Buildings are designed for the following minimum loads: Roof Live Load: 0.57kN/m2, Design Wind Speed: 80km/h to 160km/h, Design parameters of snow loads, earthquake loads, collateral loads, crane loads or any other loading condition must be specified when requesting a quotation. Loads are applied in accordance with standards applicable to pre-engineered buildings unless otherwise requested at the time of quotation.
