摘要/Abstract

摘要： 砌体结构存在着承载力低、抗震能力差等问题,所以对砌体结构的加固尤为重要。近些年在国内外兴起的纤维增强复合材料(简称FRP)以其轻质高强、耐久性好、施工方便等优点为砌体结构的加固提供了新的方向。FRP与砌体间的界面粘结性能是影响加固效果的关键因素之一。总结了国内外学者关于FRP加固砌体结构界面粘结性能的研究现状,通过收集到的试验数据对FRP加固砌体结构的极限承载力计算公式进行了校核,并对今后拟开展的研究工作提出了建议。

Abstract: Strengthening masonry structures is of great significance because of the low bearing capacity, poor seismic capacity and other problems of the masonry structures. In recent years, the rise of fiber reinforced plastic (FRP) abroad and at home provides a new direction to strengthen masonry structures by virtue of FRP′s good performances, including low weight, high strength, fine durability and easy construction. The bond performance between the FRP and the masonry structure is one of the key factors that influences the effect of strengthened structures. This paper summarizes the current research progress, made by both domestic and foreign scholars, in bond performance for masonry structures strengthened by FRP sheets and finds that there are fewer researches on bond performance for masonry structures strengthened by FRP sheets under a multiple-corrosive environment. We verifie the calculation formulas of the FRP′s ultimate load in strengthened masonry structure according to collected experimental data and chooses one formula which has less error. At the end of the paper, some suggestions are put forward for the future research work.

Key words: FRP sheets, masonry structure, bond performances
