Problem #2: Determine the appropriate shear reinforcement required for the beam shown (spacing of stirrups). Do not consider different loading cases for live loads and the dead load shown includes the beam's weight. Assumere 4000 psi, fy-60000 psi, and use # 3 U-shaped stirrups Note: Divide the beam into segments, 36" each where appropriate. 20k () 30k(L) 0-4 255 sy 5 #10
. 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...
Problem 2 Design a rectangular reinforced concrete beam to resist a total design moment Mu of 765 ft-kips (this includes moment due to the weight of the beam). The beam size is limited to 15 in. maximum width and 30 in. maximum overall depth. Use fc,-3000 psi and/S-60,000 psi. If compression steel is required, make d'-2.5 in.
