A simply supported rectangular beam has a width of 300mm and the

distance to the centroid of tension reinforcement is 330mm. The tension

reinforcement has an area of 2463mm.2 and the area of compression

reinforcement placed 70mm from the compression face of the beam is

1231.5mm.2, fy = 415MPa, fc'=30MPa, balanced steel ratio of 0.031.The

concentrated live load at the midspan in addition to a deadload of 20kN/m

including the weight of the beam if it has a span of 6m is__.
