| 摘 要： | 为了深入研究钢框架体系抗震性能,基于支撑杆件受力情况以及实际钢结构工程中梁柱节点连接形式,提出了基于变截面支撑-半刚接钢框架结构体系.首先,通过拟静力试验加载考察变截面支撑构件的滞回性能;进而,将试验结果与ANSYS有限元分析结果进行对比;最后,通过有限元模拟对结构体系进行时程分析,以考察体系的抗震性能.结果表明:变截面支撑的半刚接钢框架体系抗震性能良好.

| Abstract: | To further study the seismic performance of steel frame systems,this paper proposes a variable cross-section-based steel frame system with semi-rigid connections,which is based on the forces acting on struts and beam-column-joint connections in steel structural engineering. First,the hysteretic behavior of the variable cross-section brace was examined by a seudo-static test. Second,the loadings of the pseudostatic test were compared with the results of ANSYS finite element analysis. Finally,the seismic performance of the system was investigated by times-history finite element simulation. Results show that the seismic performance of the variable cross-section-based steel frame with semi-rigid connections is fine. |
