CFRP对砖墙抗震加固对比试验研究与计算分析

Comparative experimental study of masonry walls strengthened by CFRP and computation model analysis

结合一工程实践的需要,通过5片碳纤维布加固的新建墙体在周期反复荷载作用下的试验,研究了碳纤维布加固对砌体结构抗震性能的影响,以及砖砌体在碳纤维布加固后的受力特性,比较了不同加固方案对砖砌体加固效果的影响,在此基础上讨论了对碳纤维布加固砖墙抗剪承载力计算模型,并提出了简化计算公式。

The mechanical characteristic of the brick wall strengthened by carbon fiber sheet (CFS) has scarcely been studies at home. Based on the test of the brick walls strengthened by CFS in different ways,the effect of carbon fiber on seismic capacity of the brick walls is studied, which is connected with a actual civil project. A design formula is presented in the paper. At last, some distinctive advices for further researching and engineering application on FRPreinforcement of masonry wall in the future are proposed.
