【摘要】 采用遗传算法 (GA)来确定在被动控制高层建筑中每一层阻尼器合适的安装数量 .根据阻尼器的耗能特性及建筑规范对抗震结构的要求来设计评价函数 .其中选取了建筑物各层在整个反应时程加速度响应的方均根值、建筑物顶层位移响应的最大值、阻尼器的数量、及阻尼器的耗能情况来分别考虑高层建筑的震动控制、位移控制、经济性和各层阻尼器的工作性能 .通过理论分析和仿真计算表明 ,用这种方法能得到一种在被动控制高层建筑中阻尼器分布的优化设置方案更多还原

【Abstract】 In this paper, the viscoelastic dampers(VED) are used for suppressing the earthquake response of the structure. Based on the properties and characteristics of the structures with viscoelastic damper, this study applies a genetic algorithm to obtain a proper placement of the dampers in each story of the passively controlled building. The proper placement will satisfy the condition of evaluation function such as a vibration control effect, a displacement control effect, an economical effect and a damper performance for arranging the damper in each story.更多还原
