m 3: (20 points) Design the stirrup spacing for the beam shown below. Change your design between Zones 1, 2, and 3 of the beam length, using a uniform spacing in each zone. Ignore the self-weight of the beam. Loads on the beam are service loads so load factors must be applied according to ACI 318 (subscripts "d" and T" denote dead and live loads, respectively). Material strengths are fe 4,0oo psi and fy 60,000 psi. The total factored shear...

The beam shown below is subjected to a uniformly distributed load, w, over its entire length. What is the largest value of w that the beam can withstand prior to collapse? For simplicity, you may assume that w includes the weight of the beam itself.

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...
1. A rectangular beam with b 16 in., d-17 in., and h 20 in. has a clear span of 24 ft. as shown below. The beam has 1 ft. of bearing at each end, so for analysis purposes it is treated as a 25 ft. simple span (to center of bearing at each end). The beam supports an unfactored concentrated live load of P-65 kips. The beam is reinforced with 6-#10 longitudinal bars and #4 stirrups. Material strengths are fc-4,000,...
