| 摘 要： | 本文以某办公楼改造工程为实例,对框架结构负弯矩区围板型粘钢加固方法的空间效应进行研究。通过ANSYS有限元软件,采用模态分析、谱分析、时程分析对3组模型进行仿真计算,对3组模型的抗震空间效应结果进行对比分析,结果均显示围板型粘钢加固方法具有较好的抗震性能。本文结果对多层或高层结构某区域梁负弯矩加固后的局部效应具有指导意义。

| Abstract: | Taking an office building renovation project as an example,this study studied the spatial effect of reinforcing method of coaming type bonded steel in negative moment area of frame structure.Through ANSYS finite element software,modal analysis,spectral analysis and time history analysis were used to carry out simulation calculation for the three sets of models,and the seismic spatial effect results of the three sets of models were compared and analyzed.The results all showed that the method of coaming bonded steel reinforcement had better seismic performance.The results of this paper are of guiding significance to the local effects after the reinforcement of the negative moment of beams in a certain area of multi-storey or high-rise structures. |
