Re: eccentric hss braces / erection bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next] We don't deduct the area of the bolt holes when figuring the net area but you must consider shear lag. ( Ae = U x An )

You'll also find that it is impossible to fully develop the brace ( Ag x Fy ) when you consider shear lag.

Lastly you should have 2 erection holes, one to pin with while the erection bolt goes in the other.

situation - eccentric braced frame using slotted hss braces and gusset

does anybody know of a design reference or procedure for taking into account
"erection bolts"?  is there even anything to take into account?

does it matter how much hss / gusset weld is in place (along the connection)
before the bolt occurs?

does anybody specify size or location of bolts on their drawings?
