碳纤维布加固红砖砌体抗震性能研究

通过对两片碳纤维加固砌体墙体和一片未加固对比墙体进行循环分级加载的试验,研究了碳纤维布对砖墙的抗震性能改善的效应,通过采用不同的粘贴方案,研究了粘贴方式对加固效应的影响.通过对比方法,得出了碳纤维布加固试件的极限承载力和极限位移和未加固对比试件相比都大幅提高的结论.通过对三试件滞回曲线的分析,表明碳纤维加固砌体技术大大改善了砌体的抗震性能,可以作为施工技术进行推广.

A Research of Seismic Property of Masonry Structures Retrofitted by CFRP

The investigation of effect of CFRP retrofit of masonry walls on improving seismic properties of masonry walls was made by exposing two pieces of retrofitted walls and one piece of reference wall to cyclic loads.The effect of ways of applying CFRP to walls on retrofitting improvements was studied.The conclusion that the ultimate bearing force and displacement of the walls retrofitted by CFRP was improved significantly compared to reference specimen was reached by using comparison method.It shows that the CERP retrofit of masonry walls technique improved the seismic properties of masonry walls by analyzing retrogression curves of three specimens and the promotion of it into practice can be made.
