Wind load on platform
Wind load on platform
(OP)
Hi everyone,
I appreciate if anybody can direct me and show me how and in what directions I need to apply wind load on these platforms?
What category of windload in the code they belong?
The platforms are 4feet wide and the longer ones is 21' and the top one is 10' long?
They are supported by the kickers back for bldg
They are covered by metal grating
If is not much of trouble showing the wind load cases on my sketch will help me to understand better.
Thank you for your help

For lateral force I'd use the open steel frame chart in the commentary of the national building code of Canada. I've attached them. If you find them useful I can describe the input variables. They're somewhat compatible with the ASCE-7 input values prior to the last big wind revision.
Really, though, I generally try to ensure there's a nominal lateral capacity of around 5%, sometimes 10% of the vertical capacity so that I'm comfortable and that normally ends up governing in my areas. If I'm attaching to an existing structure I don't always get that luxury.
