A concrete floor slab 100 mm thick is cast monolithic with concrete beams 2.0 m on centers. The beams have a span of 4 m and have a web width of 250 mm, an effective depth of 400 mm and overall depth of 500 mm. The tensile reinforcement consists of 6-ϕ32 mm bars in two rows. Use material strengths f’c = 21 MPa and fy = 415 MPa. Calculate the ultimate bending moment strength of the T-beam in kN·m.
