Problem 1:

Design a rectangular beam to carry a uniform live load of 20kN/m and a dead load of 25kN/m (excluding its own weight) on a simple span of 6m. The beam is limited in cross-section to 250x450mm. Using f'c=21MPa, fy=345MPa, determine the reinforcement. Use a steel covering of 60mm top and bottom.

Problem 2:

A simply supported beam is reinforced with 4-28mm bars at the bottom and 2-28mm bars at the top. Steel covering to the centroid of reinforcement is 70mm at the top and bottom of the beam. The beam has a total depth of 400mm and a width of 300mm. Use f'c=30MPa and fy=420MPa.
