【摘要】 针对非线性流滞阻尼器耗能结构在Davenport谱风振激励下的随机响应及等效风荷载取值进行了系统研究.首先建立了结构的非线性运动方程;经过等效线性化后,采用复模态理论解耦,进而用随机振动方法获得结构风振响应解析式和等效风荷载取值的计算公式,从而建立了结构非线性随机风振响应的分析方法.更多还原

【Abstract】 In this paper,the random response and equivalent wind action of structures with nonlinear fluid viscous dampers subjected to Davenport random wind-induced model excitation were studied systematically. The nonlinear dynamic equations of structures were established. The complex model method was used to disconnect the equations after the equivalent linearization. The analitic solution of response random wind-induced response was obtained.更多还原
