Flexure Design?
We'd be delighted if somebody could explain this with a possible answer?
Considering flexure only, design the two-span continuous beam to support a uniformly distributed factored load of 35kN/m. The uniformly distributed load contains an allowance for the weight of the beam. The beam, which has a rectangular cross section, is to be 350 mm wide. Round the overall depth to the nearest 25mm increment, and select the size and number of reinforcing bars. Complete the design by determining the reinforcing bars required at sections of maximum positive moment. Use f 'c = 20 MPa and fy = 400 MPa.
