Round to the nearest tenth. qmax = ___ kN/m (b) Determine the maximum permissible load q based upon an allowable shear stress Tau = 60 MPa. Round to the nearest tenth. qmax = ___ kN/m
For the concrete beam shown, the modulus of elasticity is 25 Gpa for the concrete and 200 GPa for the steel. Knowing that b= 200 mm and d-450 mm, and using an allowable stress of 12.5 MPa for the concrete and 140 MPa for the steel, calculate (a) the required area As of the steel reinforcement if the beam is to be balanced, (b) the largest allowable bending moment. Hint: The design of a reinforced concrete beam is said to be balanced if the maximum stresses in the steel and concrete are equal, respectively, to the allowable stresses os and oc.
