【摘要】：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。
[Abstract]:The steel tube bundle composite shear wall is a new type of double steel plate shear wall structure, which is easy to construct and flexible in arrangement.The performance of 5 groups of T-shaped steel pipe bundle composite shear walls under reciprocating load is experimentally studied. The hysteretic curves and energy dissipation capacity are analyzed, and the shear and lateral deformation properties of the structures are also analyzed.In particular, the strain at different heights of shear wall steel plate is analyzed in detail.The ABAQUS finite element software is used to simulate the test process of T-shaped steel pipe bundle composite shear wall. The simulation results are good, which provides the basis for parametric analysis and formula derivation.Both the test results and the finite element simulation show that the bearing capacity of the composite shear wall is high and the seismic performance is superior.
