A concrete floor slab 100 mm thick is cast monolithic with concrete
beams 2.0 m on centers. The beams have a span of 4.0 m, web width of
250 mm and overall depth of 500 mm. The tensile reinforcement
consists of 6-∅20 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:
Effective flange width of an interior beam in mm = ?
Depth of uniform stress block at ultimate stage in mm to the nearest
whole number = ??
Tensile steel strain compatible with concrete strain of 0.003 in 3
decimal places = ?
