Use the interaction diagrams in Appendix A to select spiral-column cross sections to support the loads given in the accompanying list. In each case, use f'c-4,000 psi and fy=60,000psi, design the spirals and calculate the required splice lengths. Draw a typical cross section of the column showing the bars and spiral. a). Pu=750 kips, Mu= 235 kip-ft. b). Pu=525 kips, Mu= 221 kip-ft.
