摘要
对碳纤维布加固开洞墙体在低周期往复荷载作用下的抗震性能进行了试验研究及有限元模拟分析,通过对比加固前后试件的受力、变形及破坏特征等,分析了碳纤维布加固对该类砌体结构抗震性能的影响,并比较了不同方案的加固效果。研究表明碳纤维布用于低强度墙体的抗震加固是有效的。
Experimental study and finite element analysis were done under low cycling loads to research the seismic behavior of brick walls with an opening strengthened by CFRP.The reinforcement effect is studied by the comparison of the load bearing capacity,deformation and failure characteristics of the strengthened walls with those of the unstrengthened walls,and the different effects between two strengthening methods are compared as well.The study shows that use of CFRP for seismic strengthening the low intensity brick wall is effective.
