［摘要］玄武巖纖維（BFRP）是一種新型加固材料，具有延性好、耐腐蝕、抗高溫、價格低等優(yōu)點，在鋼筋混凝土結(jié)構(gòu)及木結(jié)構(gòu)加固工程中得到了廣泛應(yīng)用，但在砌體結(jié)構(gòu)加固工程中的研究和應(yīng)用較少，尚未形成成熟的理論。通過對BFRP布加固的砌體墻進行低周期反復(fù)荷載試驗，研究了采用“X”形粘貼方式和采用“#”形粘貼方式加固墻體的受力特點；在試驗基礎(chǔ)上，推導(dǎo)了玄武巖纖維布加固墻體的抗剪承載力計算公式，采用此公式計算得到的玄武巖纖維布加固墻體的抗剪承載力值與試驗結(jié)果吻合良好。

Abstract:Basalt Fiber Reinforced Polymer(BFRP)is a new kind of reinforcement material and it has the advantages of good ductility, corrosion resistance, high temperature resistance and low price. It has been widely used in reinforcement projects of reinforced concrete structures and wood structures, but there are few researches and applications in masonry structure reinforcement engineering, and the mature theory has not yet been formed. Through the low-cycle repeated load experiment of masonry walls reinforced by the BFRP sheets, the mechanical characteristics of the walls reinforced by the “X”-shaped sticking method and the "#"-shaped sticking method were studied. On the basis of the experiment, the calculation formula of the shear capacity of the wall reinforced by BFRP sheets was derived. The shear capacity of the walls reinforced by BFRP sheets calculated by this formula is in good agreement with the experimental results.
Keywords:Basalt Fiber Reinforced Polymer; masonry structure; reinforcement; shear capacity
