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.
A simply supported rectangular RC beam is to carry a uniform factored dead load of 1.2 kip/ftand a concentrated factored live load of 16 kip at mid-span. The beam self-weight is not includedin these loads. The concrete weighs 135 pcf. The span length is 25 ft. Please find the smallestsection allowed by ACI and design accordingly. Use f c’ = 5,000 psi, f y = 75,000 psi. Theexposure is interior with no weather exposure.a. Assume an arbitrary self-weight/ft of the beam.b. Find the maximum factored bending moment in the beam.c. Set up the moment equation and solve for the beam section.d. Revise the assumption if needed
