摘要
文中提出了一种基于内套筒连接的模块化钢框架梁柱节点,并对其力学性能开展有限元分析.结果表明,节点具有良好的滞回性能,能形成可靠连接.当层间位移角小于1.5%时,刚度退化较慢,等效粘滞阻尼系数趋于0;层间位移角大于1.5%时,刚度退化较快,等效粘滞阻尼系数不断增大,节点耗能能力逐渐增大.
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.
