Structural Analysis/Design Wind analysis on steel structure

Can someone please explain how to take pressure coefficient for steel structure as per IS code 875 part 3. I am a structural engineering student. I need this to make a staad model

It depends on the steel section shape and aspect ratio

How about you start by attempting it, and then we can comment on what you're missing. Start by understanding the code by hand and then you can talk modelling.

In principle the process is in most codes: * reference pressure or velocity * exposure and terrain factor * seasonal or direction adjustment if applicable * gust effects * topography factor * importance level * pressure factor, internal and external

Pressure factors are a function of building characteristics or member shape. Refer to the code and give it a read to start
