Question
.1 What is reinforced concrete? Explain. - What is meant by the modular ratio in concrete? 3 Explain what is an economic section. 4 Why is reinforced concrete so popular in building construction projects? 5 Why are the steel rods placed below and as far away as possible from the neutral axis in a reinforced concrete beam? 6 The cross section of a reinforced concrete beam is shown below. It has a modular ratio of 15. If the allowable compressive stress in the concrete is 6 MPa and the allowable tensile stress in the steel is 120 MPa, determine diameter of the three reinforcing steel rods to make the beam an economic section. 550 mm 75 O00 200
