The 5-story building design project will have its beams and slab
poured monolithically and formed a T- section as shown. Determine
the design strength φMn in accordance with the ACI/NSCP Code. The
tension steel is 9– 36 mm diameter bars (As of 36 mm = 1006 mm2)
with three bars in each of three layers. Assume 12 mm stirrups are
used, and there is 25 mm between layers. Use fc′ = 28 MPa and fy =
413.70 MPa
