摘　　要：进行了6片碳纤维片材和玄武岩纤维片材加固钢筋混凝土墙在低周反复荷载下的试验研究,并基于试验结果,对这两种类型纤维片材加固钢筋混凝土剪力墙的加固效果进行了对比分析。结果表明,玄武岩纤维片材加固剪力墙在延性及耗能能力方面表现出来的抗震性能可与碳纤维片材加固的效果媲美,有些方面甚至超过碳纤维片材加固的效果,而玄武岩纤维的价格比碳纤维的价格低廉许多,具有更好的经济性。Experimental study on 6 sheet carbon fiber sheet and basalt sheet reinforced concrete wall under low cyclic loading is carried out. Based on the test results, analysis on the two types of reinforcement effect with fiber sheet strengthening reinforced concrete shear wall is compared. The results show that, seismic performance of basalt fiber sheet reinforced shear wall is comparable to reinforcement effect of carbon fiber in some respects of ductility and energy dissipation capacity, that is better than carbon fiber reinforcement in some respects, and basalt fiber prices is cheaper than carbon fiber which has better economy.
