Understanding Loads

The performance of profiled metal cladding under load depends on its ability to resist the tension (stretching), compression (squashing), and shear (sliding) forces that it is likely to be subjected to during the lifetime of the building.

Compression, Tensile and Shear Force

 

When a beam is subjected to bending, one flange will be under compression and the other under tension.

Loads acting on roof cladding are generally classified into two types: point load and uniformly distributed load (UDL). A point load is applied to a particular area, but a UDL impacts on the total area of the roof.

Revision Category: 
3 - Substantial change to recommendation
Revision Detail: 

The clause has been revised and edited as part of the overall revision of Structure. The illustration of Profiled Steel — Flanges and Webs and some content have been moved to Profile Shape. The illustration Compression, Tensile and Shear Force was updated for clarity.
