. 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...

2. Design a square-tied reinforced concrete column to support the design loads shown below. Assume that the column must be designed with the reinforcement placed around the edges and y = 0.8. Take f.' = 4,000 psi and fy - 60,000 psi. Assume you have to use #9 bars for the longitudinal reinforcement. (35 pts.) P, - 400 kips M. -125 ft-kips
Find the maximum design axial load strength for the tied column
of cross section shown in Figure 1.1. Check the ties. Assume a
short column. Use f’c = 4000 psi and fy = 60,000 psi for both
longitudinal steel and ties. Also, draw the flexural and shear
reinforcement on a sketch.

Problem #1: Design a rectangular beam section, i.e. select b, d, h, and the required area of tension steel, A, at mid-span for a 22 ft-span simply supported beam that support its own weight, a superimposed service dead load of 1.25 kip/ft, and a uniform service live load of 2 kip/ft. Start by assuming the self-weight of the beam W-410 lbs/ft, b-0.7d, and use fc4500 psi and fy-60, 000 psi Note: Provide a detailed sketch for the final...

1. Use ρ-p0.004 and choose (you decide) the number (3 to 5) and size of steel bars from the attached table. Then proceed to determine (a) the size of the cross-sectional area, (b) the moment capacity of the RC section that you design, and (c) show where is the neutral axis on the diagram (or sketch a new one). 2.5" Given: fe 3,000 psi, fy -60,000 psi Concrete cracking strain 0.003 Initial yielding strain of...
