RESEARCH PROGRESS IN BOND PERFORMANCES OF MASONRY STRUCTURES STRENGTHENED BY FRP SHEETS

Abstract

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
