【摘要】 进行了4根高性能钢管混凝土和2根高性能钢筋混凝土柱在水平低周反复荷载作用下的试验研究。试验结果表明:支座约束及钢管径厚比是影响高性能钢管混凝土柱抗震性能的主要因素,高性能钢管混凝土柱的滞回特性、位移延性和极限相对位移受其影响显著;钢管内埋于支座并配置一定数量的抗剪钢筋是一种有效的支座嵌固形式;相同含钢率的钢管混凝土抗震性能远较钢筋混凝土试件的抗震性能好。更多还原

【Abstract】 This paper presents experimental results of 4 high-performance concrete columns filled steel tubular and 2 high-performance reinforced concrete columns under horizontal low-cyclic loading.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 calumas filled steel tubular is discassed.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 equal amount of steel,the aseismic behavior of a highperformance concrete filled steel tubular columns is much better than that of a high-performance reinforced concrete columns.更多还原
