摘　　要：通过1片未加固带壁柱砖墙和5片玻璃纤维复合材料(GFRP)加固带壁柱砖墙,其中3片采用"对拉"锚固措施,在低周往复荷载作用下进行抗震性能试验,阐述各试件的破坏特征;研究"对拉"锚固措施以及加固量对GFRP加固前后墙体的刚度及退化特性、变形性能、耗能性能等影响。研究结果表明:采用"对拉"锚固减小后期墙体刚度的衰减;"对拉"锚固对墙体变形能力有一定程度的影响,且比加固方式影响大;在极限荷载状态下,采用锚固措施对试件耗能性能的影响不明显,但在极限位移状态下,锚固措施的采用明显地改善墙体的耗能性能。It was carried out an experimental research on seismic performance of brick masonry walls with pilaster reinforced by glass GFRP when ＂through - wall＂ anchors were used. By carrying out the experiment of six pieces of brick masonry walls with pilaster strengthened by GFRP and three pieces of masonry wall with ＂through - wall＂ anchor under low reversed cyclic loading, the failure characteristic of every wall was explained ; Seismic performances such as resilience,rigidity and its degeneration, deformation, energy consumption if ＂through - wall＂ anchors were taken or not. The test results showed that using ＂through - wall＂ anchors could decrease rigidity degeneration of the wall; ＂through - wall＂ anchors had some influence on deformation of the wall, and was better than strengthening modes; Using ＂through - wall＂ anchors had little influence on energy consumption of the walls under the ultimate load, but was another thing under the ultimate displacement.
