摘要
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 has been widely used in engineering design,especially in out-of-codes high-rise building. However,the current national code only considered story drift and load-carrying capacity,while ignored the deformation of specific steel components,to keep performance of buildings. In this article,the yield and failure modes of T-stub steel beam-column connections were analyzed in detail and the physical significance of the parameters involved in the M- θ curve were described,an idealized force-deformation curve of the T-stub steel beam-column connections was obtained,which made it possible to conduct deformation control for steel components and beam-column connections.
