高层建筑斜交网格筒结构抗震概念分析
|
摘要
为了解高层建筑斜交网格筒-核心筒新型结构体系在地震作用下的抗震概念,参照工程实例建立了典型的钢管混凝土斜交网格筒-钢筋混凝土核心筒结构,采用弹塑性动力时程分析方法,基于构件塑性能发展过程明确了体系构件的屈服顺序、探讨了墙肢厚度、斜柱截面、连梁高度等因素对体系构件屈服顺序的影响,总结了内外筒抗震防线的分布特点,分析了体系弹性和塑性阶段抗侧刚度的主要影响因素和关键构件以及体系塑性耗能的关键构件。结合"三水准"抗震设防目标和体系抗震防线分布特点以及构件屈服特点,探讨了该类型结构的抗震概念。
In order to study the seismic concept of high-rise diagrid tube-core tube structures,CFST diagrid tube-concrete core tube structures were designed based on typical project.The elastic-plastic time history analysis method is adopted and the components yield order is summarized based on their plastic developing processes.The influences of wall thickness,inclined column cross section and coupling beam height on the components yield order are studied and the distribution of seismic fortification lines between tubes are presented.The main factors exerting influence on structure lateral stiffness are analyzed and the key components of structure lateral stiffness and plastic energy dissipation are achieved.The seismic concept of this structure is discussed considering the three level earthquake fortification criterion and components yield characteristics at last.
