[提要]  南京世纪塔由三种不同的结构连接结合为一个整体，在荷载作用下，相互影响，相互制约，受力十分复杂。从概念设计入手，采用ALGOR93和ANSYS5.6两种通用有限元软件进行结构计算，对世纪塔在静力和动力荷载作用下的结构特性和内力有了比较全面的了解和掌握。总结了这类结构的设计理论与方法的要点，提出了相应的设计建议。为了检验设计计算的正确性和准确性，在施工过程中对各施工阶段进行严格监控，得到了塔、索、拱应力变化及结构变形情况，验证了设计成果。

Three different structures of Nanjing Century Tower are connected to a whole one, they influence and restrict each other under dead and dynamic loads. The research on the structure began with concept design, the structure analysis is performed by ALGOR 93 and ANSYS 5.6. The structural characteristic and internal force under dead and dynamic loads are found out. For checking the correctness and veracity of design and calculation, we strictly supervised all the steps in the construction. The variation of the stresses and deformation of cable, arch and tower has been got, they checked the design of the structure.
