SEISMIC SHEAR CAPACITY OF BRICK MASONRY WALL REINFORCED BY GFRP

Abstract

By carrying out experiments on eight brick masonry walls with pilasters reinforced by glass fiber reinforced polymer (GFRP), a seismic shear capacity of brick masonry wall structures is studied in detail. First, the interaction coefficient of the pilaster ψ, modified coefficient δgfi statistic coefficient β and effective participation coefficient ζ are determined. Then, based on failure model of brick masonry walls and truss model of fiber reinforced polymer (FRP), the formulae of seismic shear capacity of brick masonry wall with pilaster reinforced by FRP are established, which have an excellent coincidence with the experimental results obtained from the test; Finally, the simplified design formula of seismic shear capacity of brick masonry wall reinforced by FRP has been proposed in this paper. The design formula can be used for further study or for design reference in brick masonry structures.
