摘要:
提出一种开菱形孔钢板墙,采用有限元程序Abaqus对开孔参数和蝶形带参数进行数值分析,研究不同参数变化对其抗震性能的影响,结果表明:增大加劲肋宽度时,小高宽比开孔墙比大高宽比开孔墙的临界屈曲荷载增幅较大;当增大开孔参数αβ,或减小γθ,初始刚度和极限承载力都将增大,但延性将变差,耗能性能减弱,建议合理选择参数满足α ≤ 0.25且β ≤ 0.25,使蝶形带以弯曲变形为主;相对而言,大高宽比的开孔钢板墙具有更好的延性和耗能效率;初始缺陷幅值较小时,其对极限承载力的影响较小。采用壁式框架对开菱形孔钢板墙模型进行简化,分析表明该模型能满足工程精度要求。
Abstract:
This paper puts forward a kind of steel plate wall with diamond openings. Parameter analysis on openings and butterfly link is conducted within the environment of Abaqus to investigate the effects of different parameters on the seismic behavior of the steel wall. The results show that the augment of stiffening rib has more distinct effect on the critical buckling load of steel walls with small aspect ratio than those with large aspect ratio. When the opening parameters, α, β, increase, or γ,θ, decrease, the initial stiffness and ultimate bearing capacity tend to increase, but meanwhile the ductility will become worse. It is suggested that the opening parameters should be chosen properly to meet the demand that α and β is smaller than 0.25, respectively. This kind of wall with larger aspect ratio has better ductility and energy dissipation efficiency. The initial imperfection has indistinctive influence on ultimate carrying capacity on the condition that the imperfection amplitude is small. The wall-frame model is adopted to simplify the steel plate wall with diamond openings, which can satisfy the engineering precision.
