摘要
杭州世纪中心双塔建筑高度均为303m,在底部约1/3高度位置通过柔性的悬链网格结构连为一体。阐述了悬链网格结构的主要结构特点,展示了悬链网格结构的参数化建模过程,并重点分析了其受力及变形特点。分析结果表明,悬链网格结构的力学表现符合悬链线结构特征,其受力性能良好。采用ANSYS软件对悬链网格结构的筒形节点进行了受力分析,并根据其应力表现情况进行了针对性加强,经验证,节点可以满足承载力要求。
The height of the twin towers of Hangzhou Century Center is 303 m, and they are connected together by a flexible catenary grid structure at about 1/3 of the height at the bottom. The main structural characteristics of the catenary grid structure were expounded, the parametric modeling process of the catenary grid structure was shown, and the stress and deformation characteristics of the catenary grid structure were mainly analyzed. The analysis results show that the mechanical performance of the catenary grid structure conforms to the characteristics of the catenary structure, and its mechanical performance is good. ANSYS software was used to analyze the force of the cylindrical nodes of the catenary grid structure, and targeted reinforcement was carried out according to their stress performance. It is verified that the nodes can meet the bearing capacity requirements.
