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. C...
Reinforced Concrete Design Please answer it with good write . Problem 1: The reinforced concrete cantilever beam shown is subjected to a concentrated load P- 2 kips, at its free end. Determine the development length of the shown bars using the detailed and simplified methods for the following cases: a) straight bars b) 90 hooks c )180, hooks The column width is 22 inches. Concrete cover is measured from the concrete surface to the center of the reinforcement. fc 4...
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...
