[摘要]为评价HR-EPS(Hai Rong-Expanded Polystyrene)模块剪力墙结构的抗震性能,通过试验与数值模拟相结合的方法,对配筋率及轴压比不同的足尺HR-EPS模块剪力墙试件进行抗震性能研究。研究结果表明:墙体配筋率的提高,可以大幅增强足尺HR-EPS模块剪力墙的水平承载力;随着墙体配筋率的增加,墙体的刚度、位移延性系数以及耗能能力均有所增加,刚度退化速率有所降低;模拟结果与试验数据基本吻合,适当地增加轴压比可提高试件的耗能能力及其刚度,使其抗震性能有所提升;并根据试验结果对已有公式进行修正,给出了足尺HR-EPS模块剪力墙抗剪承载力计算公式。

Abstract:In order to evaluate the seismic performance of HR-EPS(Hai Rong-Expanded Polystyrene) module shear wall structure, seismic behaviors of full-scale HR-EPS module shear walls were evaluated under different reinforcement ratio and axial compression ratio through a combination of the experimental study and numerical simulation. The results show that the horizontal bearing capacity of full-scale HR-EPS module shear wall increases obviously with the increase in the wall reinforcement ratio. The stiffness, displacement ductility coefficient and energy consumption capacity of full-scale HR-EPS module shear wall increase while the stiffness degradation rate decreases with the increase in the wall reinforcement ratio. The results of simulation are basically consistent with experiment, and the energy consumption capacity and stiffness of specimen can be improved by increasing axial compression ratio properly, and the seismic performance is improved at the same time. The calculation formula for shear bearing capacity of full-scale HR-EPS module shear wall is deduced according to the results and existing formulas.

Keywords:HR-EPS module shear wall; reinforcement ratio; low-cyclic reversed loading experiment; seismic performance; full-scale test
