A 15 in. x 26 in. rectangular RC beam (shown in figure below) supports a service uniform dead load of 1.3 kip/ft and a service uniform live load of 1.6 kip/ft. The dead load includes the beam’s self-weight. Design the reinforcement required for maximum moments and show the design in sketches. Use f c ’ = 4,000 psi and f y = 60,000 psi. The beam is used in an open parking garage and is exposed to weather. a. Find factored maximum bending moments. b. Design for max. negative moment. c. Design for max. positive moment. Hint: Assume an initial beam shape (b, d), then solve for the needed reinforcements at the maximum negative and positive factored bending moments. This is like the class example.
