SITUATION. A composite beam is shown in the figure. The 10-meter long beam is a W16x40, A36 steel spaced 2-meters on-center and the concrete slab is 150 mm thick. Shear connectors ensure that there is a full composite action. -be- Properties of W16x40: A = 7612 mm² d = 410 mm x = 216 x 106 mm² Given: fy = 248 MPa ts = 130 mm fc = 21 MPa Nominal strength of each shear connector, Q₁ = 50 kN Strength-reduction factor, p = 0.90 TT I 1. Evaluate the effective flange width. 2. Compute the ultimate positive flexural strength of the composite section 3. Evaluate the required number of shear connectors.
