Please answer the situation 1 only 

Situation 1. A 7.5 m long simply supported beam has a cross sectional area of b = 400 mm by h = 550 mm. The beam has
reinforcement of 2-28 mm compression bars and 4-28 mm tension bars, each located 70 mm from the extreme concrete
fiber. f'c = 24 MPa, fy = 414 MPa. Use NSCP 2015.
a. Determine the nominal moment capacity of the beam.
b. Determine the additional concentrated service live load that can be applied at 2m from the left support if the dead load
including the weight of the beam is 20 kN/m
Situation 2. Design a T-beam for which bw = 300 mm and d = 550 mm. The beams are 4.5 m long and spaced at 3 m on
centers. The slab thickness is 100 mm. Dead load Moment = 700 kN-m (including the weight of beam) and Live load
Moment = 80 kN-m. f'c = 28 MPa and fy = 414 MPa. Use NSCP 2015.
a. Determine the Steel Area of the beam
