巨型结构自振特性的影响因素分析

ANALYSIS OF FACTORS INFLUENCING DYNAMIC CHARACTERISTICS OF MEGA-STRUCTURE

  • 摘要: 巨型结构体系是适应超高层建筑发展趋势和特点的新型结构体系,该文选取上海环球金融中心大厦为研究对象,该结构采用巨型框架结构、钢筋混凝土筒结构和伸臂钢桁架组成的三重结构体系抵抗水平荷载,进行了整体结构模型的振动台试验,并利用有限元软件ANSYS进行了自振特性分析,理论分析与试验结果进行了验证,探明了该巨型结构体系的动力特性和主要影响因素,可供工程设计人员在结构选型和方案设计时参考。

     

    Abstract: Mega-structure is a new kind of structural system for high-rise buildings. The main advantage of mega-structure is high capacity to resist lateral loads. Shanghai World Financial Center Tower is selected in the paper to study the features of Mega-structure. The lateral loads are resisted by a system containing mega-frame, reinforced concrete core and outrigger trusses. Shaking table model test is taken and a 3-D finite element analysis is carried out using ANSYS. The study demonstrates some dynamic characteristics of the mega-structure and some influencing factors, which might be useful for structural system selection.
