摘要

摘要: 内填钢板墙的双肢C型钢框架是一种新型的框架结构体系，建立三层该类框架进行低周往复加载试验，分析其破坏形态、模式及抗震性能，试验结果表明：钢板墙的屈曲起到了良好的耗能作用，内填钢板墙可以提高双肢C型钢框架的承载力和刚度，层间位移角满足抗震设计要求。在试验的基础上，考虑钢板墙的高厚比、钢板墙高宽比、框架柱刚度系数等参数，采用验证后的有限元模型，分析各个参数下内填钢板墙框架的抗震性能，得到了一定的参数设计建议。

Abstract: The cold-formed double C steel frame filled with steel plate walls is a new type of frame structural system. Three-story frame specimens of this new type frame were made and tested under low cycle reversed loading. The failure form, failure mode and seismic behavior of the frame were analyzed. The test results show that the frames with infill steel plate walls possess good capacity of energy-dissipation when they buckled, and the infill steel plate walls can improve the bearing capacity and stiffness of the cold-formed double C steel frame and ensure that the inter-story drift satisfies the requirement codified in the seismic design code. Based on the test results, a finite element model was established, and the parametric study on seismic behaviors of cold-formed double C steel frames filled with steel plate walls was performed considering the variation in height-thickness ratio of steel plate walls, height-width ratio and stiffness coefficient of frame column. At last, design suggestions were proposed based on the finite element parametric analysis.
