喷射GFRP加固开门洞砌体墙片的试验研究
首发时间:2010-11-03
摘要:本文通过3开门洞砌体墙片(素墙、碳纤维布加固和喷射玻璃纤维聚合物(SGFRP)加固)在低周往复荷载作用下的试验,研究了喷射玻璃纤维聚合物加固和碳纤维布加固对开门洞砌体结构抗震性能的影响,比较了两种不同加固方案对砌体的抗剪承载力、抗震性能、延性等各方面的加固效果。结果表明,SGFRP加固较粘贴碳纤维布加固,墙片具有更高的抗剪承载力和更好的抗震性能,故更适合用于开门洞砌体墙片的抗震加固。

Experimental study on masonry walls with door opening strengthened by SGFRP
Abstract:Based on the test of the three masonry walls with door opening that is the plain wall, the two walls respectively strengthened by CFRP and SGFRP, the effect of Sprayed Glass Fiber-reinforced Polymer Composites and CFRP on seismic capacity of masonry walls is studied,and the reinforcement effect of the two ways about lateral-load-carrying capacity, seismic-resistance performance and ductility is compared. The result indicates that SGFRP Reinforcement has higher lateral-load-carrying capacity and better seismic-resistance performance , so it is more propitious to the seismic-resistance reinforcement of masonry walls with door opening.
Keywords: SGFRP CFRP reinforcement masonry wall with door opening
