【摘要】 提出了一种基于遗传算法的黏滞阻尼器空间位置优化方法,运用GATBX遗传算法工具箱编制遗传优化程序,通过编制空间三维协同弹塑性动力时程反应分析程序来对结构上设置多个黏滞阻尼器的空间位置进行优化,以控制偏心结构在多维地震作用下的扭转联耦反应。选用两种目标函数,以一个6层的偏心结构为算例,比较阻尼器的均匀布置和优化布置的结构动力响应。优化布置阻尼器可以更有效地减小最大层间位移角,使层变形趋向于均匀,采用遗传算法计算所得结构控制效果较好。更多还原

【Abstract】 Based on the Genetic Algorithm(GA) theory,GA optimization procedures is made by using GATBX toolbox in MATLAB,and the optimal distribution of structures with fluid viscous dampers is carried out with the dynamic elastoplastic seismic response analysis program.Comparing the response of the structure before and after optimal distribution,the result shows that the response of the structure can be effectively reduced under the condition of constant total damping coefficient.更多还原
