Abstract: The height of the twin towers of Hangzhou Century Center is 303m, and they are connected together by a flexiblecatenary grid structure at about 1 / 3 of the height at the bottom. The main structural characteristics of the catenary gridstructure were expounded, the parametric modeling process of the catenary grid structure was shown, and the stress anddeformation characteristics of the catenary grid structure were mainly analyzed. The analysis results show that themechanical performance of the catenary grid structure conforms to the characteristics of the catenary structure, and itsmechanical performance is good. ANSYS software was used to analyze the force of the cylindrical nodes of the catenary gridstructure, and targeted reinforcement was carried out according to their stress performance. It is verified that the nodes canmeet the bearing capacity requirements.
