摘要：钢管混凝土边框组合剪力墙是一种新型组合剪力墙。本文进行了2个1／4缩尺的高强混凝土
剪力墙模型的低周反复荷载试验，模型l为普通钢筋混凝土剪力墙，模型2为钢管混凝土边框组合剪
力墙。在试验研究基础上，对比分析它们的承载力、延性、刚度及其衰减过程、滞回特性、耗能能力及
破坏特征，建立了组合剪力墙的承载力计算模型，计算结果与实测结果符合较好。研究表明，钢管混
凝土边框高强混凝土组合剪力墙与普通剪力墙相比抗震性能显著提高。

Abstract：Composite shear wall with concrete filled steel tube columns is a new kind of composite shear wal1． Experimental
studies on the seismic behavior of two 1／4 scale high strength concrete shear wall models under low frequency
circle load are done． One model is traditional reinforced concrete shear wall，the other is composite shear
wall with concrete filled steel tube columns． Based on the experiment，load-carrying capacity，ductility，stiffness
and its degradation，hysteretic property，energy dissipation and failure phenomena of each shear wall are contrastively
analyzed．The formulas of load-carrying capacity are established．The results obtained from the formulas and
those from experiment are in good agreement．The results show that the seismic behavior of high strength concrete
composite shear wall with concrete filled steel tube columns has been developed evidently compared with the traditional
reinforced concrete shear wal1．
