| 摘 要： | 为探讨基于分灾模式抗震加固思想的可行性,本文在一个5层3跨的混凝土框架结构两端分别添加附加框架和分灾框架后,对结构进行pushover分析,以研究加固前后结构的抗震性能.分析结果表明:当采用与原结构有良好匹配关系的分灾框架时,可以将原结构的抗震能力由7度提高到8度,分灾框架可以先于原结构破坏,体现了基于分灾模式抗震加固的思想；同时说明了分灾框架应具有合理的结构形式,以保证其有足够的结构延性.本文的结论,可以为基于分灾模式抗震加固方法的深入研究提供参考.

| Abstract: | In order to discuss the feasibility of seismic retro fi tting based on damage-reduction mode,this paper analyses a five-story frame s tructure with three crosses which adds damage-reduction frame in each side,by using pushover analysis to compare the seismic performance.The studies show tha t a reasonable damage-reduction frame which mate the original structure will im prove the seismic capability of original structure from seven degree to eight de gree,damage-reduction frame will damage fast than original ... |
