A simply supported reinforced-concrete beam has to resist a maximum factored moment of M* = 210 KN-m. Given that f’c = 32 MPa, fy = 500 MPa and that the maximum possible width for the beam is 240 mm: a. Establish an appropriate structural depth ‘d’ for the beam b. Determine the total depth ‘D’ of the beam for a FRL of 90 minutes c. Find the area of steel Ast required to resist the moment and select the rebars. – Include the two checks required for a satisfactory design.
