带钢连梁混合双肢剪力墙结构抗震性能参数分析

PARAMETERS ANALYSIS OF SEISMIC BEHAVIOR FOR COUPLED SHEAR WALLS STRUCTURE WITH STEEL BEAM

随着高层建筑飞速发展,剪力墙结构普遍应用。传统的RC剪力墙刚度较大,延性不足,不利于结构抗震。带钢连梁混合双肢剪力墙结构是一种新型高效的抗侧力结构,由钢连梁来代替RC连梁,并将梁端嵌入钢筋混凝土剪力墙墙肢内而形成。利用大型有限元软件ANSYS进行带钢连梁混合双肢剪力墙结构在单调水平荷载作用下的抗震性能参数分析。研究结果可为其抗震设计提供理论参考,并加快其工程应用。

With the rapid development of high-rise building structures, shear wall is being used widely. Traditional RC shear wall is not conducive to seismic, because of the stiffness and poor ductility. Hybrid Coupled Walls （HCW）are a new and efficient anti-lateral force structure comprised of two reinforced concrete wall piers connected with steel coupling beams distributed over the height of the structure. The seismic performance was analysed under the quasi-static by using the finite element software ANSYS. The results would provide theoretical reference for seismic design and speed up its engineering applications.
