摘要:
介绍了巨型框架多功能减振结构体系的工作原理和优化分析方法.改变调谐比和阻尼比等关键参数,通过时域和频域分析,研究了巨型框架多功能减振结构体系在地震和风荷载作用下的减振效果.结果表明,与普通的巨型框架结构体系相比,巨型框架多功能减振结构体系在地震和风荷载作用下的反应显著降低,具有良好的减振效果.
Abstract:
A principle and optimization method of multifunctional vibration-absorption megaframe structures is presented. By changing the tuned ratio and the damping ratio, the effectiveness of multifunctional vibration-absorption megaframe structures under earthquake and wind excitation is discussed in both time and frequency domains. The results show that the response of multifunctional vibration-absorption megaframe structures under earthquake and wind excitation is much less than that of normal megaframe structures.
