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。The ratio of story shear rigidity as well as the equivalent lateral rigidity ratio of story above the transfer story to the story under the transfer story should be designed properly to avoid the transfer story becoming weak story, thus the shear walls and the columns in the large base will not yield before the elements above the transfer story ; ( 2 ) the translation - torsion coupled effects and the vibration in the plane should be considered in analysis of structure with large base and muti - towers
轉換層的設計除應控制層剪切剛度比外,還應控制轉換層上部與下部結構的等效側向剛度比以避免薄弱層出現在框支層,保證地震作用下落地剪力墻和框支柱不先於轉換層上部結構進入屈服狀態;大底盤多塔樓結構的分析必須考慮平扭耦聯振動和樓板平面內振動的影響。The influence of a uniform electric field on the motion and energy of the electrons in atoms is known as the stark effect.
