| Summary: | 碩士 === 國立成功大學 === 土木工程學系碩博士班 === 95 === This study investigates a numerical model on the Reinforced Concrete(RC) beam-column joint strengthened by the carbon fiber reinforced polymer (CFRP). At the beginning, a three-dimentional(3-D) nonlinear finite element analysis is used to simulate the behavior of interior and exterior beam-column joints without CFRP. There are six experiments to perform the the parametric studies including the concrete compressive strength, axial load, and the simulation of steel. Then, a 3-D nonlinear finite element analysis is used to investigate the behavior of interior beam-column joints with CFRP. Finally, the numerical results demonstrate that the concrete compressive strength make an important role in beam-column joints. In this research, a pre-rehabilitation way for using CFRP is suggested. A numerical model on RC beam-column joint strengthened by CFRP is also proposed.
