摘要

The paper presents the results of an experimental program focusing on the effect of buckling of reinforcingbars on the post-peak behavior of reinforced concrete columns in seismic regions. Full-scale, square crosssectioncolumn specimens were tested with stirrup spacing (4-, 6-, 8- and 12-bar diameters) being the mainvariable. All specimens were subjected to displacement cycles of increasing amplitude with constant axialforce. Test results show that specimens behave satisfactorily to the imposed displacement history up to theoccurrence of bar buckling. Column behaviour after bar buckling is conditioned by stirrup spacing andpeak tensile strain of the bars at the instant of reinforcement buckling.
