REINFORCEMENT OF DAMAGED FRAME JOINT WITH CARBON FIBER

摘要：

　　Most structure is damaged in earthquake areas,and research on seismic performance of damaged RC frame joints is limited.The study will take load in end of column with force-displacement mixed control on the condition of changing axial compression ratio by Quasi-static test of cyclic loading.It focuses on the analysis and comparison of indexes which have important effect on the seismic performance,such as hysteretic behavior,strength degradation,stiffness degradation,ductility,energy dissipation capacity,failure modes between undamaged joint and column-damaged joint after reinforcement with carbon fiber,and obtains the effect of axial compression ratio for frame joint strengthened with carbon fiber.Research results will be applied to reinforcement of damaged structure,has a broad business value.
