针对一非对称双塔连体结构,变换连接体与主体结构的连接方式,并建立了动力分析模型和三种连接工况下连体结构的振动方程,分析了结构动力特性随连接方式的变化规律,分析结果表明:自振周期随连接的减弱及振型的增加而逐渐变大。对该结构体系沿连体设置方向输入El Centro1940地震波,采用动力时程分析方法分析连体结构的抗震性能,研究结果表明:连体结构中采用合理的模型并引入耗能装置可以大大减小结构在地震作用下的动力响应,提高连体结构的抗震性能。
Aiming at an asymmetrical twin-tower conjoined structure, the connection between the connection body and the main structure was changed, and the dynamic analysis model and vibration equations of the conjoined structure under three connection conditions were established. The dynamic characteristics of the structure were analyzed with the change of connection mode. The law and analysis results show that the period of self-vibration gradually becomes larger as the connection weakens and the mode shape increases. The El Centro 1940 seismic wave is input along the set direction of the structure and the seismic performance of the conjoined structure is analyzed using the dynamic time history analysis method. The results show that the use of a reasonable model and the introduction of energy dissipation devices in the conjoined structure can greatly reduce the structure. The dynamic response under earthquakes enhances the seismic performance of connected structures.
