Re: Steel Beam Reinforcing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Randy,

I think you should consider using flat bar welded to the underside of the
beam flange, Assuming that your bean is composite, and that you have enough
shear studs cast in this should be enough.  If you are not composite you'll
need to weld some angle or flat bar (attached to the web and top flange) to
provide the necessary compression resistance.
