A W310

60 steel beam (see Appendix B) has a C250

45 channel bolted to the top flange as shown in Figure P9.56/57. The beam is simply supported at its ends and carries a concentrated load of 90 kN at the center of an 8-m span. If pairs of bolts are spaced at 600-mm intervals along the beam, determine

(a) the shear force carried by each of the bolts.

(b) the bolt diameter required if the average shear stress in the bolts must be limited to 75 MPa.
