Q22. A C10X15.3 steel channel (textbook Table A4) is bolted to a 1/2″ thick gusset plate with 3/4″ diameter A325-N high strength bolts and standard size holes.

Q23. All connected material is ASTM A36 steel.  Determine the maximum allowable load, P, for this connection.

The allowable load P is based on the minimum condition of bolt shear, bearing failure at bolt holes of the connected member, tensile rupture through the net area of the connected member, or tensile yielding of the gross area of the connected member.

Allowable bearing stress = Fp = (1.2)(Fu) = (1.2)(58) = 69.6 KSI

Allowable tensile rupture stress = Ft = (0.5)(Fu) = (0.5)(58) = 29 KSI

Allowable tensile yield strength of A36 steel = (0.6)(Fy) = (0.6)(36) = 22 KSI
