【摘要】 本文应用最优控制理论提出了高耸结构模糊随机风振反应振型控制的一般设计计算方法。文中解决了结构风振振型控制研究中几个尚未解决的问题。它们是:(1)建立了相应于各振型的广义脉动风力的成型滤波器;(2)在计入风干扰随机性的同时考虑了实际脉动风的模糊性;(3)提出了结构风振振型消极控制的计算公式和积极控制的实现途径;(4)确立了以结构风振反应可靠性为风振控制效果检验的准则。更多还原

【Abstract】 This paper presents the general design method for model control of fuzzy random vibratien responses of highrise structures under wind Ioads.In the paper,some problemes unsol- ved in the research for wind vibration control of structures are solved.These are: (1)the filter of generalized fluctuating wind forces for the mode shapes is established. (2)the fuzzy properties of real fluctuating wind are considered.(3)the calculating- formulas of passive control and the achieving way of active control for wind vibr- ation responses are presented.(4)it is determined that reliability of the structural vib- ration responses under wind loads is the criterion examining the effects for wind vibra- tion control.更多还原
