［摘要］通過對4片無筋砌體磚墻在低周往復荷載作用下的試驗，研究了玄武巖纖維加固砌體墻的抗震性能；分析了加固前后墻體的受力性能、滯回特性、剛度退化、耗能及變形能力等變化規(guī)律。研究表明：玄武巖纖維加固可以較大程度地提高磚墻的極限荷載和變形性能、有效延緩墻體裂縫發(fā)展、改善砌體脆性，從而顯著提高結構的抗震性能；采用玄武巖纖維加固砌體結構是一種經(jīng)濟有效的結構加固方法。

Abstract: Based on the test of 4 unreinforced masonry walls under low cycle reversed loading, the seismic performance of masonary walls strengthened with BFRP were analyzed, mainly including the bearing behavior, hysteretic property, stiffness degeneration, energy dissipation and deformation capability before and after strengthening. The experimental results show that the BFRP strengthening technique can increase the ultimate load and the deformation capability, effectively postpone the development of cracks, ameliorate the brittleness of masonry, and improve the energy dissipation properties of masonry walls. It is an economic and effective method to strengthening masonry structures with BFRP.
Keywords: BFRP; masonry; seismic performance; hysteretic property; load-bearing capacity
