strength of short steel beam 9hl150
 

strength of short steel beam (h/l>1/5)
i remeber the strength ( or allowance stress) should time a coefficient (<1)， but i forgot what's the exact.
can you give me a answer?
if you are in the us and have access to aisc, see provisions on design of "plate girders".
thanks.
i can't find in aisc codes
