摘要

运用随机平均法,对Maxwell粘滞阻尼器耗能结构的随机风振响应与等效风荷载取值进行了研究.研究通过建立结构运动方程,利用基于随机平均分析完全相同的等效准则,建立了上述阻尼器的等效阻尼计算公式,最后,基于频域法,得出结构设计响应和等效设计风荷载取值的计算公式,并给出了算例.
The random wind-induces response and equivalent wind action of dissipation structure with Maxwell viscous dampers are studied by the stochastic averaging method.The dynamic equation of structure is established firstly;then by using the stochastic averaging method and the equivalent criterion of stochastic averaging analysis,the analystic formulas of equivalent damping of Maxwell viscous dampers are established;finally,the formulas of the structural wind-induced response and equivalent wind action are obtained by using frequency method.And an example is given to show how to use this method.
