某框架结构建筑震害分析及加固设计研究
|
摘要
根据地震现场考察,介绍了云南盈江5.8级地震某7层框架结构建筑的震害情况;从施工、设计等方面系统的分析了震害原因,并在此基础上进行了震损修复及抗震加固设计,加固设计从建筑物的结构体系受力特性出发,采用规范化的标准加固设计模块,分析对比加固前后计算结果,保证了加固实施的合理性及安全性,总结了防御和减轻震害应注意的一些问题,可为同类工程提供参考。
Based on the investigation of seismic disaster area cause by Yingjiang M5.8 earthquake,the damages of a 7 storey framework construction are introduced,the reason of seismic damage was systematic analyzed from aspect of construction and design.In addition,seismic damage rehabilitation and seismic strengthening design have been made on the basis of structural system mechanical characteristics,with normalized and standardized strengthening design module,analyzed the calculation results between before and after strengthening,guarantee the security and rationality of strengthening implementation.In the end,matter need attention in disaster prevention and reduction are summarized.This can be used as a reference for similar projects.
