钢管束组合剪力墙是一种新型的双钢板剪力墙结构,施工方便、布置灵活。对5组T字型钢管束组合剪力墙在往复荷载作用下的性能进行了试验研究,分析其滞回曲线及耗能能力,同时分析了结构的剪切变形与侧向变形性能,尤其对剪力墙钢板不同高度处应变进行了详细分析。采用ABAQUS有限元软件对T字型钢管束组合剪力墙试验过程进行模拟,模拟效果良好,为进行参数化分析及公式推导提供基础。试验结果与有限元模拟均表明:T字型钢管束组合剪力墙承载力高、抗震性能优越。

The bundled lipped channel-concrete( BLC-C) composite wall is a new kind of double steel plate shear wall with the advantages of convenient construction and flexible arrangement. Experiments were carried out on five T-shaped steel tube bundle composite shear walls under cycle load to analyze their hysteretic curve and energy-dissipating capacity. The shear and lateral deformation property of the structure were analyzed,especially the strain at different heights of the shear wall. The finite element software ABAQUS was used to simulate the experiments,and the simulation result is good. It lays the foundation of parametric analysis and formula derivation. A series of researches show that Tshaped steel tube bundle composite shear wall has high bearing capacity and great seismic performance.
