A doubly reinforced concrete beam section has an effective depth of 625mm and a width of 350 mm. It is reinforced with compressive bars at the top having an area of 1500 sq mm and 4970 sq mm tension bars at the bottom with a steel covering of 62.5 mm both on top and bottom bars. Balanced steel ratio =0.0285, f'c=27.58 and fy=413.4 MPa 1) Compute the compression block. a) 188.64 mm b) 181.35 mm c) 174.83 mm d) 190.55 mm 2) Compute the ultimate moment capacity of the beam. a) 908.00 KN m b) 935.00 KN m c) 988.00 KN - m d) 1008.00 KN m 3) Compute the safe concentrated live load that the beam could carry at its midspan if it has a service dead load of 30 KN/m on a span of 6m. a) 244.70 KN b) 352.50 KN c) 281.30 KN d) 300.20 KN
