针对已经完成的柱脚采用半刚接自复位装配式钢框架1层子结构(原模型为4层)进行拟动力试验,采用ABAQUS有限元分析软件建立4层单跨有限元模型进行动力时程分析,分析钢框架的位移响应、开口变化、滞回曲线和各部位的应变发展状况,并与试验结果进行对比分析。分析结果表明:有限元和试验结果较为吻合,证明了半刚接自复位钢框架的优越性和有限元分析的可靠性,为今后进一步开展研究打下良好的基础。
A pseudo-dynamic test was carried out on the finished column with one-layer subassembly of semi-rigid self-resetting assembled steel frame (the original model was 4 layers). Four-span single-span finite element model was established by ABAQUS finite element analysis software Analysis and analysis of the displacement response of the steel frame, the change of opening, the hysteresis curve and the strain development of each part, and compared with the test results. The analysis results show that the finite element and experimental results are in good agreement, which proves the superiority of semi-rigid self-resetting steel frame and the reliability of finite element analysis, laying a good foundation for further research.
