自复位平面钢框架有限元分析对比

摘要

利用有限元软件 ABAQUS 对两个采用普通刚接节点、自复位节点的单榀、两跨4层钢框架进行了弹塑性拟静力循环加载分析，对比分析了各框架每层的滞回性能及塑性变形特性，得出了自复位平面钢框架复位性能良好和塑性变形较小的结论。%The paper adopts the finite element software ABAQUS to undertake the elastic-plastic quasi-static cyclic loading analysis, compares and analyzes hysteretic performance and plastic deformation features of each layer of framework, and concludes the self-centering plane steel framework has better centering performance and less plastic deformation.
