2. A 6 meter long simply supported reinforced concrete beam has a width of 350 mm and an overall depth of 470 mm. The beam is reinforced with 2-28 mm compression bars on top and 4-28 mm tension bars at the bottom, each located 70 mm from the extreme concrete fiber. Concrete strength f'c = 20.7 MPa, and steel yield strength fy = 415 MPa. Determine the additional concentrated live load that can be applied at midspan if the dead load including the weight of the beam is 20 kN/m.

2. A 6 meter long simply supported reinforced concrete beam has a width of 350 mm and an overall depth of
470 mm. The beam is reinforced with 2-28 mm compression bars on top and 4-28 mm tension bars at the
bottom, each located 70 mm from the extreme concrete fiber. Concrete strength f'c = 20.7 MPa, and steel yield
strength fy = 415 MPa. Determine the additional concentrated live load that can be applied at midspan if the
dead load including the weight of the beam is 20 kN/m.
