O = 5. Reinforced concrete beams 300 mm wide and 500 mm deep are spaced 2.5 m on centers. The beams support a slab 100 mm thick carrying a superimposed dead load of 3 kPa and a live load of 4.8 kPa. In the typical frare shown below, columns E and H are removed so that girder BEHK supports bears DEF at E and GHI at H. Concrete weighs 24 kN/m2. Use 20mm bars and 10 mm stirrups. Concrete strength is f'c = 21 MPa and steel yield strength fy=275 MPa 6 m 6 m В. С A 2.5 m D E IF 2.5 m G H 2.5 m J K 5.1. Design the amount of reinforcement for a maximum positive moment in beam DEF. Present your answer in mm2 and the number of 20mm bars required. Consider T-beam action if possible. 5.2. Design the amount of reinforcement for a maximum negative moment in beam DEF. Present your answer in mm2 and the number of 20mm bars required. Consider T-beam action if possible.
