摘要
某中小学教学楼为典型的80年代建造的砌体教学楼,鉴定结果显示基础稳定,上部结构材料强度不足,部分构造设置不合理。在结构抗震加固再设计中,从概念上分析结构加固的合理性;合理地确定地震作用影响系数,对加固前后的结构进行整体计算分析;对重要及复杂的部分节点进行补充设计。
A typical masonry building of middle and elementary school was built in 1980's.In the process of re-design seismic strengthening the building,First,the seismic appraisal of the building is assessed,the results show that the stable base,the lower strength of material in the upper part,and non-reasonable structural design.Then we analyze the rationality of the structural reinforcement and determine the seismic effect coefficient.The structure calculation was run for before and after strengthening building,and the nodes of the important and complex part were re-design.
