The one way reinforced concrete slab spans dimension (long side = 6 m and short side = 3 m). It is simply supported at its left edge, fully fixed at its right edge, and free of support along the two long sides. Reinforcement provides design strength [( Mn =22 kN.m/m) in positive bending and (Mn = 33 kN.m/m) in negative bending at right edge]. Using yield line theory, find the factored load Wu uniformly distributed over the surface that would cause flexure failure?
