地震作用下双塔弱连接连体结构受力性能研究

Study on the Mechanical Characteristics of Two-tower Weakly Connected Joint Structures Subjected to Seismic Action

对单塔楼和双塔连体结构的抗震性能进行了比较分析和研究,采用三维有限元模型,通过3个算例,分别计算了单塔楼、连接体与主体结构固接的对称双塔楼和与主体结构弱接的对称双塔楼结构,从结构振型、位移、剪力3个方面分析了弱连接体对双塔连体结构抗震性能的影响,得出了一些有益的结论,可为同类工程设计参考.

The comparative analysis is carried on the earthquake resistance performance of the single tower and the two-tower connected structures,the changes of periodic,vibration mode and dynamic responds of the two-tower weakly connected structures are mainly discussed, some results are gotten, these are references for the similar designs.
