本文探讨受斜拉弹簧阻尼器模型装置(CTSD)控制的高层建筑结构在顺风向脉动风激励下的随机风振反应问题.文中将高层建筑和CTSD控制机构作为一个整体的耦合体系.同时考虑体系阻尼的非正交性,建立了一种以复模态组合为基础的新的随机反应分析方法——复模态状态空间法;导得了受控体系状态反应以及结构各层反应统计解的统一表达式.通过对框架型高层建筑的实例计算以及与非耦合实振型反应结果的比较表明,该方法是很有理论和实用价值的.
This paper discusses the random wind-induced vibration response of a high-rise building structure controlled by inclined cable spring damper model device (CTSD) in the presence of turbulent turbulence. In this paper, the high-rise building and the CTSD control system are considered as a whole coupled system. For the non-orthogonality of damping, a new stochastic response analysis method based on the complex modal combination is established—the complex modal state space method; the state reaction of the controlled system and the statistical solution of the reaction at each layer of the structure are derived. The expressions show that the method is very theoretical and practical in value by comparing the results of the example calculation of a high-rise building with frame type and the result of the uncoupled real vibration type.
