Purlins are horizontal structural members in roofs that support the load from the roof deck or sheathing and transfer it to the main structural elements such as beams or rafters. The design of purlins, according to IS 800: 2007 (Indian Standard Code of Practice for General Construction in Steel), involves calculating the load-carrying capacity, bending stresses, deflections, and ensuring adequate safety against buckling and shear.
Purlins can be checked for :
- C-sections
- Z-sections (commonly used for their strength and ability to overlap).
- I-sections or angles (depending on design requirements).
