CFRP加固震损开洞填充墙RC框架抗震性能试验
Seismic performance test of CFRP reinforced seismic damaged masonry infilled RC frames with openings
摘要
Abstract
To investigate the seismic performance of carbon fibre reinforced plastics(CFRP)retrofitted seismic damaged masonry infilled reinforced concrete(RC)frames with openings,the low-cycle loading test of two dam-aged masonry infilled RC frames with openings and one seismic damaged RC empty frame strengthened with CFRP are conducted.Compared with previous reinforcement,the damage degree of the frame strengthened with CFRP is significantly reduced,and the bearing capacity and ductility are improved significantly.According to the test data,hysteresis curves,skeleton curves,stiffness degradation,ductility and energy dissipation capacity and other seismic performance parameters of seismic damage specimens strengthened with CFRP are obtained.The results show that:the bearing capacity,ductility and energy dissipation capacity of the seismic damaged masonry infilled RC frames with openings specimens strengthened with CFRP have been improved.The stiffness degradation rate of the specimens are slower than that of the unreinforced specimen.Although the initial stiffness of the specimen is slightly lower than that of the unreinforced specimens.It can also reach or even exceed the level of seismic performance before damage.The strengthened seismic damaged specimens show great seismic performance.关键词
