Question

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.

Answer #1

A simply supported reinforced concrete beam has a width (b) of
14 inches, and an effective depth (d) of 24 inches. It is
reinforced with 3 # 8 bars. Assume 60-ksi steel and 3000-psi
concrete. Determine the resisting moment (Mr) in ft-k that this
beam can safely sustain.
Problem 2
The beam given in Problem 1 has a span of 21 ft. It is supposed
to carry a uniformly distributed service dead load of 3.7 k/ft, in
addition to its...
