摘要
本文提出主、附结构依靠连接元件组成联合减震控制体系。建立了体系的计算模型和运动方程。给出了体系减震控制的优化目标、约束条件和连接元件布置的优化设计方法。最后,以一双塔高层结构为例,进行数值计算和优化,结果分析表明本文的方法可行,优化后的减振效果明显。
A combined structure control system, which is composed of primary structure and auxiliary structures connected by linker to reduce the vibration of the system due to earthquake is proposed in this paper. The calculating model and motion equations of system is established. A optimal object, restrained factor and the method of optimization of connect elements location are alslo given. Finally, the numerical calculation and analysis are carried out to a twin-tower high-rise structure. The results show that the method in this paper is feasible, and the optimization effect to reduce the vibration of the system is obvious.
