A composite beam has a cross section as shown in the figure below. The moment due to dead load, prior to concrete attaining strength is 581 kN-m. Subsequent to concrete attaining its strength, an applied load induces an additional moment of 410 kN-m and a vertical shear of 170 kN. Assume that the beam is not shored when the slab was poured and assume that creep and shrinkage stresses are negligible. Assume full composite action. Determine the longitudinal force at the junction of the slab and steel beam due to vertical shear.
