摘要
杭州国际会议中心(HICC)主楼是一幢外观呈球状的高层钢结构,但结构受力体系仍为双向框架-支撑体系。然而不同于笛卡尔直角坐标系的双向框架-支撑体系,该框架的两个方向为极坐标系的两个主轴方向:径向和环向。该结构在具有一般框架结构特征的同时,也呈现出一定的球状结构特征。利用ANSYS单元生死技术对该结构进行施工模拟分析,通过了解施工过程中结构的力学状态来为施工过程提出合理建议,并考察了分层加载和结构刚度逐层修正对结构分析的影响。另外,也详细阐述了施工模拟分析的意义。
The main tower of Hangzhou International Conference Center（HICC） is a spherical high-rise building.This is a two-way frame-brace system building.Differing from the two-way frame-brace system of Cartesian right-angle coordinates system,the two directions of this frame is the principal axis directions of polar coordinates system： radial direction and circumferential direction.Besides brace-structure characteristics,this structure has some spherical structure characteristics.In this paper,the birth and death element technology of ANSYS was used to simulate construction process of this structure.By understanding the mechanical state in construction process of the structure,some reasonable proposals were made for the real construction.And the effect to structure of story by story loading and structural stiffness matrix step by step updating were studied.Besides,the significance of the construction simulation was introduced in detail.
