Question

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 beyond the bend is 2-in. The beam-columrn joint is enclosed by ties at 6-in on center. of the beam. The beam has #3 double-leg stirrups at 7.5-in. throughout the beam and the beam-column joint b) be developed in the beam using straight anchorage? The bar ends 2-in from the end Notice that except for the side cover of 2 in, a clear cover of 2-in is assumed Do draw sketches to back up your calculations 18 6-in Column reinforcement omitted for clarity 48 18
