摘要
针对内填耗能Y型偏心钢支撑加固的RC框架的结构整体受力情况,采用ABAQUS有限元软件进行非线性有限元分析,研究了结构体系的承载力、耗能破坏模式、抗震延性和抗侧刚度等性能,并进一步分析耗能梁段长度、腹板高度、腹板厚度、翼缘宽度及支撑翼缘宽度等相关设计参数对结构体系受力性能的影响,得出了相应的的影响规律,为相关人员进行研究和工程设计提供理论依据。
As to the load-bearing performance of Y-eccentrically bracing-retrofitting RC frame structure, the finite element software named ABAQUS was adopted to make a nonlinear FEM analysis of the loading-carrying capacity, energy-dissipation failure mode, seismic ductility and stiffness of the structure system. Furthermore, the influence of the relevant design parameters of the length, height and thickness of the energy-dissipation beam, the width of flange and width of flange of brace on the load-bearing performance of the structural system. Based on the analysis, the paper presented some relevant influence rules, which would provide the theoretical references for relevant researchers and designers.
