| 摘 要： | 对 4个钢管高性能混凝土柱和 2个钢筋高性能混凝土柱进行了抗震试验。试验发现 ,钢管径厚比和支座约束等是钢管高性能混凝土柱抗震性能的主要影响因素 ,特别是对钢管高性能混凝土柱的滞回特性、位移延性和极限相对位移的影响明显 ;钢管内埋并配置一定数量的抗剪钢筋是一种有效的支座嵌固 ;在柱截面尺寸及用钢量相同的条件下 ,钢管高性能混凝土柱的抗震性能比钢筋高性能混凝土柱好得多

| Abstract: | This paper presents the seismic test results of 4 high\|performance concrete filled steel pipe columns and 2 reinforced high\|performance concrete columns.This paper also discusses the effect of diameter\|thickness ratio and restraint at supports on seismic behavior,especially on hysteretic behavior,displacement ductility and ultimate relative rotation of high\|performance concrete filled steel tubular columns.The test results show that setting a number of shear reinforcements in the buried steel pipes is an effective built\|in support;and on condition of the same size of column section and equal amount of steel,the aseismic behavior of a HPC filled steel pipe column is much better than that of a high\|performance RC column. |
