矩形钢管混凝土端柱-混凝土剪力墙组合墙体是一种新型抗侧力构件。从弹性静力、弹塑性有限元和模型试验三方面对组合墙体的力学性能进行研究,分析了组合墙体的承载力、延性、刚度及其衰减过程、滞回特性、耗能能力及破坏特征。这种新型组合剪力墙及筒体可有效地将混凝土剪力墙侧向刚度和承载力大的优势与钢管混凝土柱抗震延性好的优势结合起来,矩形钢管柱与混凝土剪力墙之间的抗剪连接键能够可靠工作,工程应用效果良好。
Rectangular concrete-filled steel tube column - concrete shear wall composite wall is a new type of anti-side force components. The mechanical properties of composite wall are studied from the aspects of elastic statics, elasto-plastic finite element analysis and model test. The bearing capacity, ductility, stiffness and damping of composite wall, hysteresis characteristics, energy dissipation capacity and damage are analyzed feature. The new combined shear wall and cylinder can effectively combine the advantages of large lateral rigidity and bearing capacity of concrete shear wall with the good seismic resistance of concrete filled steel tubular columns. The combination of rectangular steel column and concrete shear wall Shear link can work reliably and works well.
