As per IS 875 (Part 3), if the value of the design wind speed (Vz) is 35.2 m/s, determine the basic design wind pressure (pz).

The strength and size specification of a butt weld is primary specified by its:

As per IS 800, the maximum bending moment for the design of purlins can be taken as (where W is the total distributed load including wind load on purlins and L is the effective span/centre distance of supports):
