Abstract
This paper proposes a modular steel frame beam-to-column joint with inner sleeve connection,and finite element model was de-signed to analyze its mechanical properties.The results showed that the joint has good hysteresis performance and reliable bearing capacity.When the story drift ratio is lower than 1.5%,the stiffness degradation is slow,and the equivalent viscous damping coefficient is closer to ze-ro.As the story drift ratio is greater than 1.5%,the stiffness degradation grows faster,the viscous damping coefficient and energy dissipation capacity continues to increase with the increasing with story drift ratio.关键词
