【摘要】 本文通过四个钢管高强混凝土叠合柱与一个普通高强混凝土柱在周期往复荷载作用下抗震性能的试验研究，比较了两种柱的抗震能力和破坏形式；然后根据试验结果，分析了叠合柱受水平荷载作用时，外围钢筋混凝土与核心钢管混凝土之间轴力及水平力的分配关系；最后讨论了外围混凝土强度等级及名义轴压比等参数对叠合柱抗震性能的影响更多还原

【Abstract】 In order to study the seismic behavior of laminated columns, four laminated columns and one common high-strength column were tested under reciprocating load Then according to the experimental results, the distribution relationships of axial load and horizontal force between steel tube filled with high strength concrete and outer laminated concrete are analyzed Finally, the influence on seismic performance of laminated column by some parameters, such as nominal axial compression ratio and strength of outer laminated concrete, is studied更多还原
