angle design
angle design
(OP)
I have a situation where I have to have an equal leg single angle that is in bending. I am using asd 89....and the appendix addresses these angles. My problem is that when I use equation (5-4)...Fob is equal to 450...this appears way to big when I try to plug it back into (5-3 a or b)...my unbraced length is 60"...and its a 3x3 1/2 angle....I just need to have a capacity to check it against....thanks for any help provided.





RE: angle design
You would use Eq. 5-3b and with that I get Fb = 29.125 but limited by 0.66Fy = 24ksi....thus use 24 ksi
