纤维片材加固砌体结构研究分析
|
摘要
砌体房屋的抗震加固问题日益突出,大量的老砌体房屋以及分布于世界范围内的各种历史优秀建筑都亟需进行修复加固和保护,对纤维片材加固砌体结构的研究具有十分重要的现实意义。本课题通过对不同类型砖墙和砖柱的碳纤维布加固试验研究,对比加固前后试验数据,分析了碳纤维布加固对该类砌体结构抗震、抗压性能的影响,比较了不同方案的加固效果,并提出了可用于实际工程的理论计算公式。研究表明,碳纤维布对提高墙片抗震性能效果明显。
The problems of seismic strengthening of masonry structures are becoming more and more outstanding.The great number of old masonry structures and varies of historic buildings which are spreading all over the world are in need of strengthening and repair urgently.The study on masonry structures strengthened by carbon fiber sheet is very important and significant.The strengthening effect on the seismic capacity of several kinds of brick walls and carrying capacity of several brick columns was studied in the paper respectively,through the comparison of the data in the experiments before strengthened and the strengthened ones,and the different effect of different strengthening ways was compared as well,besides,calculation formulae supposed to be used in practical project were provided.The study indicates that the effection of masonry structures strengthed by carbon fiber sheet was obvious.
