5. Composite Beam Capacity A 7.5 m span simply supported composite beam uses a concrete slab with an overall thickness of 130 mm and a corrugated dovetail profile depth of 50 mm, supported on a 457x 152×52 UB in S275 steel. (a) If the slab utilises a concrete with a concrete strength, fck, of 25 N/mm2 what is the Moment Capacity of this composite beam assuming full shear connection? [10 marks] (b) If shear studs are placed in every second trough, as shown on the figure, and the trough spacing is 150 mm (i.e. the studs are spaced 300 mm apart), what would be the reduced Moment Capacity, if the Design Shear Capacity of one stud in this profile type is 92kN ?
