A simply supported beam with a span of 8m is to carry, in addition to its weight, a superimposed dead load of 18kN/m and a live load of 30kN/m both over the entire span.
The beam has a rectangular section which is to be singly reinforced. Given pt=1.1% design and detail the steel reinforcement for the section where the moment is maximum
Take R=d/b=1.5, density =24kN/m3, fc=20Mpa and use N36 bars only. Exposure Classification A1 applies. use R10 bars only for closed ties maximum aggregate size=10mm
