For a steel building i am looking at, i have 40 wind load cases and 10 snow load cases.
When applying the following load combination 1.2D + 1.6S + 0.5W, does this mean i need to consider 400 loadcases? I really hope not!
Well Answer very easy. You have to consider whatever needs to be considered
If you do not know which of your 40 wind load cases are the worst ones you need to consider them all
same for the 10 Snow cases
usually by 'engineer thinking' you can lower the number of load cases.....
