2. A beam with the following cross section has to be designed to resist factored positive moment demand, Mu, equal to 1500 kip-in. Due to architectural reasons, the dimensions of the section are pre-defined as below. Also, only #8 and #9 bars can be used as longitudinal reinforcement and #4 bars as transverse reinforcement. The specified cover is 2". The compressive strength of the concrete is 4000 psi and grade 60 is used for the steel bars. The cross section...

Figure 2 shows a simply supported beam and the cross section at mid span. The beam supports a uniform service (unfactored) dead load consisting of its own weight plus 1.4 kips/ft and a uniform service (unfactored) live load of 1.5 kips/ft. The concrete strength is 3500 psi, and the yield strength of the reinforcement is 60,000 psi. The concrete is normal-weight concrete. For the midspan section shown in Figure 2, compute фМп and show that it exceeds Mu. WD 1.4...

A rectangular steel-reinforced concrete beam supports a uniformly distributed load of 875 lb/ft (including the beam weight) for a span of 24 ft. The breadth of the beam is 12 in. Concrete with a specified compressive of 3000 lb/sqin and grade 60 steel for tensile and web reinforcement are specified. Four longitudinal tensile bars are to be used. If required, No. 3 stirrups will be used. Determine the minimum effective depth of the beam section (Round to the nearest inch...
