From above analysis, the thesis gets conclusions as following : ( 1 ) the frequencies of multi - tower building are so dense and the coupling in each mode is so evident that the cqc method instead of srss should be used to calculate the seismic action effect ; ( 2 ) torsion effects is distinct between the modes of asymmetry multi - tower structure and it is necessary to take translation - torsion coupling into account ; ( 3 ) the effect of the enlarged base rigid on the seismic properties is very big, the rigid ratio of the enlarged base to towers in asymmetry multi - tower structure should be designed in a proper range ; ( 4 ) the distribution of plane rigid is asymmetry because of the asymmetry layout of towers. the torsion effects of structure not only result in large torsion internal force in vertical element resisting lateral displacement, but also make large influences on the stress of transfer plate and near floors, thus it is necessary to strengthen those floors
通過上述分析，得出以下主要結論：多塔樓結構存在頻率密集現象，各振型間耦聯效應明顯，地震作用計算應採用cqc組合原則而不能簡單地採用srss組合原則；非對稱多塔結構的振型中，扭轉作用明顯，平扭耦聯效應值得考慮；裙樓剛度對整體結構的抗震性能影響很大，非對稱多塔結構宜控制裙樓與塔樓剛度比在適宜的范圍；非對稱多塔易導致平面剛度分佈不均勻，結構扭轉效應不僅在豎向抗側構件中引起較大的扭轉內力，對轉換層樓板應力有較大的影響，且延續至相鄰樓層，對相應樓層均應採取相應的加強措施。 -
Then the base was enlarged and the large steps were progressively filled in with a second layer of smaller steps, creating a shape much closer to a true pyramid
其次是擴大基礎部分，逐級加大下層踏步，這樣使上層踏步小於下層逐步構造出與真正金字塔接近的形狀。 -
On the original base, we have increased the investment of equipment and enlarged the production capacity
本廠在原有的基礎上，加大設備投資，擴大生產能力。 -
One of the tower levels will be used for required building equipment and machinery air conditioning, elevator machinery, water storage, etc. the six floors in the base of the building will be used for a new modern enlarged eastern shopping mall, as well as several restaurants
本商廈重建后， 1 - 6樓共1 . 8萬平方米將建成一個集購物餐飲娛樂為一體的「銷品貿」 shopping mall ，以與步行街上的小店鋪展開錯位競爭。 -
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 horizontal stiffness of isolated layer is reduced, the effect of the base - isolated structure is clear. and the damping is enlarged to reduce the displacement of the superstructure
隔震層的水平剛度越低，隔震效果越明顯，隔震層位移隨之增大，需增大隔震層阻尼來減小位移。
