中文摘要：

提出了连排钢管混凝土柱带钢板耗能键组合剪力墙,它由钢管混凝土连排柱、柱间钢板耗能键、钢板耗能键外包混凝土条带三种单元组合而成。进行了4个不同设计参数试件的低周反复荷载试验研究。分析了各试件的承载力、刚度及其退化过程、滞回特性、延性和破坏特征,探讨了分灾耗能机制。研究表明：连排钢管混凝土柱带钢板耗能键组合剪力墙,承载力较大,后期刚度较稳定;混凝土条带在开裂与闭合过程中消耗地震能量,钢板耗能键通过弯剪变形消耗地震能量,钢管与混凝土条带共同工作协同耗能,具有良好的抗震耗能机制;这种新型组合剪力墙具有较强综合抗震耗能能力。

英文摘要：

A novel composite shear wall with paralleled CFST columns and steel plate energy-consuming connectors is put forward in this paper. It consists of three units, which are paralleled CFST columns, steel plate connectors between columns, and outside concrete strips. The experimental study on 4 specimens with different design parame- ters is carried out under low cyclic loading. The load-bearing capacity, stiffness and its degradation, hysteretic properties, ductility, and failure characteristic of specimens are compared and analyzed. The damage reduction mechanism is discussed. Results of the experiments show that the new wall has high load-bearing capacity and its later stiffness is stable. The energy is consumed during the cracks opening and closing on the concrete strips, so do the steel plate connectors during their flexure-shear deformation. The new composite shear wall has good seismic mechanism, and it can consume energy when the steel tubes work with the concrete strips. It has great integrated seismic energy-dissipating capacity.
