3)
A concrete floor slab 100 mm thick is cast monolithic with concrete beams 2.0 m on centers. The beams have a span of 4.2 m, web width of 250 mm and overall depth of 450 mm. The tensile reinforcement consists of 4-∅25 mm bars in two rows with 25 mm vertical clear spacing. Use material strengths f’c = 21 MPa and fy = 415 MPa.
Calculate the following considering a T-geometry:
