| 摘 要： | 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。

| Abstract: | Aimed to a unsymmetrical connected double-tower structure,the connected style of the main structure and the connection was transformed,the corresponding dynamic analysis model and the twin towers connected structure vibration equation with three linking conditions were constructed,and the change laws of dynamic performance were analyzed while the connection style was changed.The results indicated that,natural vibration period become gradually bigger as the vibration mode gradually increased and the connecti... |
