摘要
Abstract
The finite element model of BCJ-RCS was established by using the verified finite element numerical method,and the low-cycle reciprocating loading analysis was carried out to study its hysteretic performance and stress-strain development law.The effects of flange width-to-thickness ratio,web height-to-thickness ratio,web waveform ratio and web half-wave number on BCJ-RCS hysteresis curve,skeleton curve and equivalent damping coefficient were further explored.The results show that the hysteretic curve of the new beam-column joint was full and had good energy dissipation capacity.In the process of reciprocating loading,the plastic strain was concentrated in the energy-consuming beam section,and the main components such as beams and columns were not yielded,and the design goal of replaceability after earthquake was successfully achieved.The width-to-thickness ratio of the flange and the height-to-thickness ratio of the web had a significant effect on the seismic performance of BCJ-RCS,while the web waveform ratio and the half-wave number of the web had little effect.关键词
