Behaviour of wide reinforced concrete beam in shear

Wide reinforced concrete beams were been used in buildings to reduce reinforcement congestion and floor heights for a required headroom. The beam in most of these cases is wider than that of the supporting columns. Consequently, their shear capacity might be effected and differ from that of conventi...
