A computer software was developed for inelastic analysis of reinforced conc
rete columns under combined axial compression and monotonically increasing
lateral loads. The software incorporates effects of concrete confinement, s
teel strain hardening, reinforcement buckling and secondary deformations du
e to P-Delta effect. Hinging of column critical region and progression of h
inging along column height are considered. Inelastic deformation components
due to flexure and anchorage slip are included. The input consists of colu
mn geometry, material properties, and loading. The results are presented in
a graphical form in terms of moment-curvature, force-displacement, and mom
ent-anchorage slip relationships. Axial force-moment interaction diagram is
also plotted as part of the output. The program was verified extensively a
gainst available experimental data. (C) 2000 Elsevier Science Ltd. All righ
