Q. reinforced concrete beam 230 mm wide by 500 mm overall depth is reinforced with 4 bars of 12 mm diameter at an effective cover of 50 mm. Using M 20 grade concrete and Fe 415 steel, estimate the moment of resistance of the section. If the beam is simply supported over an effective span of 5m, find the maximum uniformly distributed load the beam can carry, inclusive of its own weight.
