Question

1. A singly reinforced rectangular beam is to be designed with the effective depth approximately 1.5 times the width, to carry a live load of 1.5 kip/ft in addition to

it's own weight. The span is 24 feet and the boundary conditions are simply supported. The reinforcing steel has a yield strength of 40 ksi and the concrete has a compressive strength of 4 ksi. Determine the dimensions (b, d and h) and steel reinforcing bars using a design reinforcement ratio of(0.75)pTC and a (b/d) ratio of ~0.7. Include a sketch of the final cross section.
