A reinforced concrete slab (see Figure Q2) is reinforced with 13 mm bars spaced 160 mm apart at d = 105 mm from the top of the slab. The modulus of elasticity for the concrete is E = 25 GPa, while that of the steel is E, = 200 GPa. Assume that allowable stresses for concrete and steel are dac = 9.2 MPa, and Gas = 135 MPa 2.1 Determine the maximum permissible positive bending moment for a 1 m wide strip of the slab [15] 2.2 What is the required area of steel reinforcement 'A,', if a balance condition must be achieved? What is the allowable positive bending moment? (Recall that in a balanced design, both steel and concrete reach allowable stress values simultaneously under the design moment).
