Question
Figure P5.3 shows the column reinforcement for a 16 in. diameter concrete
column, with f, = 75,000 psi and f = 8000 psi. Analysis of the building frame
indicates a required A, = 7.30 in? in the lower column and 5.80 in? in the upper
column. Spiral reinforcement consists of a in. diameter rod with a 2 in. pitch.
Column bars are to be spliced just above the construction joint at the floor level,
as shown in the sketch. Calculate the minimum permitted length of splice.
