HELP! Problem 6 Development Length (30 pts.) The required reinforcement steel area "As" for the lightweight reinforced concrete beam of figure 3 is 2.88 si. The No. 8 top bars are uncoated. Compute the development length (d), İffy 60,000 psi and fc 3.500 psi. a) Use the simplified equation Table 8-1) b) Use the ACI Equation 25.4.2.3a (Equation 8-10) c) Use the ACI Equation 25.4.2.3a with Ktr 0 (Equation 8-10) 18 3" 3@4 123 3" 448 bars 3.14 in2 26...
Problem ll The figure below shows a cantilever beam with b = 12-in containing 3-No 7 bars that are anchored in the column by standard 90° hooks. fc 4500 psi (normal weight) and fy- 60,000 psi. If the steel is stressed to fy at the face of the column, can these bars: a) be anchored by hooks into the column? The clear cover to the side of the hook is 2 34 -in. The clear cover to the bar extension...
Please answer in numerical order. 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...
