| 摘 要： | 采用平面杆系模型并用静力凝聚法消除结构耦联的水平自由度和转角自由度,结合两个算例的竖向振动模态分析和时程响应分析,探讨了大底盘双塔楼连体结构在竖向地震作用下的振动特性,对比了大底盘双塔楼结构有无连体结构形式的计算结果,得出了这种结构形式在竖向地震作用下的一些特性和具有参考价值的结论。

| Abstract: | This paper used plane link element and eliminated the coupling of the horizontal and rotational displacements to the vertical displacements. Based on the mode analysis and time-history analysis of two examples,the vibration characteristics of the connected twin-tower structures with enlarged base in vertical earthquake excitation was discussed in this paper, and the calculating results of the structures with or without connecter, both with enlarged base are compared. At last, some characteristics subjected to vemcal earthquake action and conclusions of referenced value were obtained in this paper. The useful results for structural seismic design are presented. |
