摘要
苏州IFC地下4层,地上93层,建筑高度450m,结构体系为巨型框架-伸臂桁架-混凝土核心筒体系,属超限高层结构。除对设计准则、结构体系与弹性分析结果简单介绍外,重点介绍了超高层结构设计的诸多关键问题,如抗震性能指标、框架承担剪力比例、巨柱的承载力设计、风荷载下舒适度与TMD设计等,希望为类似的超高层工程的结构设计提供经验。
Core-outrigger-mega frame system is used in Suzhou IFC with 93-story, 450m-tall,which is beyond Chinese code limit. Besides simple introduction on design principle, structure system and analysis, key techniques including performance based design criteria, frame shear ratio, capacity check of mega column, human comfort criteria under wind induced vibration and TMD design were presented in details. It can be reference for design of similar super high-rise buildings.
