A simply supported concrete beam is to be designed to span 8m. The beam is required to resist a dead load of 40 kN/m (which includes an allowance for self-weight) and an imposed load of 20 kN/m Calculate the ultimate design load that the beam will be required to resist and hence calculate the ultimate design moment. (10 Marks] b) Choose an appropriate depth and width of the beam. [5 marks] c) Calculate an appropriate amount of reinforcing...
