[提要]  南京世紀(jì)塔由三種不同的結(jié)構(gòu)連接結(jié)合為一個(gè)整體，在荷載作用下，相互影響，相互制約，受力十分復(fù)雜。從概念設(shè)計(jì)入手，采用ALGOR93和ANSYS5.6兩種通用有限元軟件進(jìn)行結(jié)構(gòu)計(jì)算，對(duì)世紀(jì)塔在靜力和動(dòng)力荷載作用下的結(jié)構(gòu)特性和內(nèi)力有了比較全面的了解和掌握?？偨Y(jié)了這類結(jié)構(gòu)的設(shè)計(jì)理論與方法的要點(diǎn)，提出了相應(yīng)的設(shè)計(jì)建議。為了檢驗(yàn)設(shè)計(jì)計(jì)算的正確性和準(zhǔn)確性，在施工過(guò)程中對(duì)各施工階段進(jìn)行嚴(yán)格監(jiān)控，得到了塔、索、拱應(yīng)力變化及結(jié)構(gòu)變形情況，驗(yàn)證了設(shè)計(jì)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.
Keywords: tower; cable; stayed  arch; calculation; analysis; structural  design; structural  test
