摇摆墙体外加固中小学校框架结构抗震性能分析
|
摘要
采用外加摇摆墙的体外加固方法加固一个不满足抗震要求的四层中小学框架结构,通过对不同加固方案的加固结构进行弹性和弹塑性地震反应分析,研究地震作用下不同加固方案对结构的抗震性能影响,分析结果表明,外加摇摆墙可使原结构各楼层的位移角趋于均匀化,增设摇摆墙之后结构的塑性铰状态相对减缓。
The paper adopts the external swaying wall consolidation for the four-storey middle and primary frame structure failing to meet the seismic requirements,researches the influence of various consolidation schemes for the seismic performance of the structure under the effect of earthquake by analysis the elastic and elastic-plastic earthquakes of the consolidated structure with various consolidation schemes,and proves by the analysis result that the external sway wall can make displacement angles of floors homogenized,and the plastic hinge model after the addition of the swaying wall is relatively relieved.
