1. A simply supported beam with overhang is shown with equal load P is applied at the end of the beam on each side. Neglecting any "long time" effects, develop nominal M vs curvature (q) for this beam. In particular, identify four points on the M-o diagram: a) first cracking, b) service load level, c) yielding of reinforcement and d) ultimate capacity. The allowable stresses at service level are 0.4 fe for concrete and 0.4 fy for steel. Assume the beam has adequate amount of stirrups to prevent shear failure. Assume a clear cover of 30 mm and 10M stirrups. P 400 3000 7000 3000 to 4#30M f - 30 MPa £, = 400 MPa 08S P. 1.
