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
In this paper, the seismic performance of four steel tubular high-strength concrete superposed columns and an ordinary high-strength concrete column subjected to cyclic reciprocating loads is studied. The seismic capacities and failure modes of the two columns are compared. Then, according to the test results, the superposed columns are analyzed. When the horizontal load is applied, the distribution relationship between the axial force and the horizontal force between the peripheral reinforced concrete and the core steel tube concrete is discussed. Finally, the influence of the external concrete strength grade and the nominal axial compression ratio on the seismic performance of the superposed column is discussed.
