In this paper, three - tower building with name of oriental tunes square in xiamen is analyzed by the international current program sap2000, considering seismic action in two directions. by structural modeling and calculation, the characteristic of vibration of the multi - tower structure is analyzed, the influences of the rigid ratio of the enlarged base to top tower and translation - torsion coupled effects among several towers are investigated, the inter - story displacement, displacement of the top tower and deformation of tower ' s base floor in x and y major orientation under earthquake action are contrasted with those under wind load. at last, the distributing characteristics of stress of transfer plate and of the normal, shearing stress of mostly vertical elements under earthquake action are studied
本文以具有3個塔樓的廈門東方時代廣場為分析對象，採用國際通用有限元分析軟體sap2000進行結構建模和分析，考慮雙向地震動輸入，研究結構的振動特性，分析底盤與塔樓剛度比對結構的影響以及多塔之間的扭轉效應和平扭耦聯作用，對比風荷載和地震作用下塔樓在兩個結構主軸方向的層間位移、頂點位移以及塔樓底層的變形，分析地震作用下轉換層樓板的應力分佈特點及主要豎向構件的正應力和剪應力分佈特點。 -
The second part involves the coupled design optimization of thermal structures, which takes the thermal displacement, thermal stress, thermal buckling and thermal vibration into account, hi this part, the main contents are the theory and computational schemes of sensitivity analysis, the techniques of software design and the algorithms of design optimization for the coupled system. the research work will be introduced with the following chapters
這里的耦合有三方面的含義： 1 ）在系統分析中考慮熱傳導對結構分析的耦合作用； 2 ）在靈敏度分析中，針對直接法和伴隨法兩種計算格式分別考慮了熱傳導對結構或結構對熱傳導的耦合作用； 3 ）在優化設計時，優化模型中同時考慮了熱傳導約束和結構響應約束的共同作用。
