Question

. Deisgn a reinforced concrete cross-section with unknown dimensions Problem 1 Design the steel reinforcement for the beam shown in Figure 1 that supports its own self-weight, a uninformly distributed dead load, a uniformly distributed live load, and a live point load located at midspan. In your solution, you should select the area of reinforcement, the number and size of reinforcing bars, and the section depth in order to receive full credit. Assume J 5,000 psi, fy 60,000 psi. 16 in L- 16 ft 30 in L 32 ft WoL 0.9 kip/ft (self-weight not included) WL 1.2 kip/ft Pu 3.5 kips Figure 1 Problem2 A 14 ft long cantilver beam supports its own self-weight in addition to a service dead load of 1.4 k/ft. The beam also supports a service live load of 2.0 k/ft. Design the bean section (i.e., select b d, h, and reinforcement details). Assume -7,000 psi and f, -60,000 psi.
