RECENT ASSIGNMENT

The construction of a sports centre uses the beam in Figure 3. The beam is an 800WB122 unstiffened section. The WB section is of grade 300PLUS. The design loads cause bending about the major axis, a. Use the applied design loads to check the adequacy of the unstiffened WB section in shear.
b. If stiffeners with a spacing of 1150mm are incorporated into the design of the beam: determine the new shear strength of the beam.
