Question
Compute for the (a) maximum permissible ultimate moment that can be carried by the section if
it is reinforced only at the bottom, given a Rectangular beam that is 300 mm wide with 450 mm
effective depth. fc' = 32 MPa and fy = 420 Mpa. Also, Compute the (b) maximum permissible
ultimate moment that can be carried by the section if it is doubly reinforced. Assume that the
compression bar area is a quarter of the tension bars, and located at 75 mm from the top-most
fiber.
