中文摘要：
提出了圆钢管混凝土边框内藏桁架剪力墙结构.该新型剪力墙包含2种组合：不同受力体系（钢管混凝土、钢桁架与剪力墙）组合和不同材料（型钢与混凝土）组合,形成了多重组合剪力墙.进行了3个1/5缩尺中高剪力墙的低周反复荷载试验.在试验研究基础上,对比分析了剪力墙的承载力、延性、刚度及其衰减过程、滞回特性、耗能能力及破坏特征,建立了圆钢管混凝土边框内藏桁架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：圆钢管混凝土边框内藏桁架剪力墙与普通剪力墙相比抗震性能显著提高.
英文摘要：
Shear wall with concrete filled round steel tube columns and concealed bracing is presented.This new composite shear wall consists of two kinds of composition.One is composition of two bearing systems,including concrete filled steel tube frame,steel truss and shear wall,the other is composition of two materials,including steel and concrete.So it is a multiple composite shear wall.The experiment was carried out on the seismic behavior of three 1/5 scale mid-rise shear walls.Based on the experimental study,the stiffness and its attenuation,bearing capacity,ductility,hysteretic property,energy dissipation and failure phenomena of each shear wall are contrastively analyzed.The formulas of bearing capacity and stiffness are established.The results obtained from the formulas and those from experiment are in good agreement.The results show that the seismic behavior of shear wall with concrete filled round steel tube columns and concealed bracing is improved evidently compared with traditional reinforced concrete shear wall in high axial-load ratio.
