reduced section for bolting through compression flange?
i know this is probably a silly question. how do you typically handle bolting through the compression flange of a w section. i see lots of info on effective net section for tension members in the aisc but no talk about compression side of beams. i could find the reduced ix easily enough but would a hole in only 1 side of the flange affect buckling state? i am an eit and havent done alot of steel design. thanks.
no problem. nothing to consider. compression/buckling of a
it is typically not a problem for the beam itself but for the connecting elements. ltb of beams occurs over a defined length of the member (lb). bolts in the compression flange will not greatly effect this because of the small area they take up in the beam.
you do need to make sure that the bolts are working by checking for shear, bearing, etc., also the connecting elements like the gussets or angles you are using to connect the
got it, thanks for the quick replies. thats what my gut was telling me. i will check all other aspects of the connections (shear, bearing ect.)
