基于性能的抗震设计思想越来越多地运用于工程设计尤其是超限高层建筑结构抗震设计中,但现行国家规范对性能设计的规定,仅是考虑宏观层面的层间位移角及使用承载力对构件进行控制,而没有深入到构件和节点的变形。详细分析了T型钢梁柱节点屈服模式和破坏模式,对该节点弯矩-转角曲线所涉及参数的物理意义进行阐述,得到T型钢梁柱节点标准化力-变形曲线,从而使对构件和节点进行变形控制成为可能。
Performance-based seismic design ideas are increasingly used in engineering design, especially in over-limit high-rise building seismic design, but the provisions of the current national norms on performance design, only consider the macroscopic layer displacement angle and the use of bearing capacity Control the component without going into the deformation of the component and node. The yield mode and failure mode of the T-shaped beam-column joint are analyzed in detail. The physical meaning of the parameters involved in the moment-moment curve of the node is expounded. The normalized force-deformation curve of the T-beam joint is obtained, Node deformation control possible.
