摘　　要：喷射玻璃纤维聚合物(SGFRP)加固3片带构造柱砖墙,通过低周往复水平荷载作用下的抗震性能试验研究,描述了试验墙体的破坏形态,探讨了喷射玻璃纤维聚合物加固后带构造柱砖墙的加固效果。试验结果表明,加固对墙体的开裂位移、极限位移和承载能力都有较大的提高,并能有效改善墙体的延性和耗能能力。不同的喷射GFRP厚度和短切纤维长度对砖墙抗震加固效果也有一定的影响,通过对比不同加固方式对墙体抗震性能的影响,提出合理的加固建议。In this paper,3 masonry walls with tectonic columns are strengthened by Sprayed Glass Fiber Reinforced Polymer（SGFRP）,and a research of the seismic behavior of them tested by horizontal cyclic loading experiment is presented.The failure mode and strengthening effects of the masonry walls strengthened by SGFRP are discussed.The results show that the cracking displacement,ultimate displacement and bearing capacity of the reinforcing walls increase greatly,and the ductility and dissipation capacity of them also improve significantly.Comparing the strengthening effects of the walls when the thickness of SGFRP and the length of fiber are different,some reasonable reinforce suggestions are proposed.
