加入多维隔减震装置建筑结构的水平向与竖向综合优化
Horizontal and vertical integrated optimization on building structure with multi-dimensional earthquake isolation and mitigation device
本文首先简要介绍了振动台试验及多维隔减震装置,然后对振动台试验进行了有限元模拟,并通过有限元模拟和振动台试验得到的自振频率、加速度和层间位移反应的对比分析,证明了有限元模型的正确性。在此基础上,建立了参数优化模型,利用遗传算法对多维隔减震装置进行了参数优化设计,并对装置参数取最优解和非最优解时结构的动力反应进行了对比分析,结果表明,优化分析后建筑结构的水平向加速度、水平向位移和竖向加速度均明显降低。
Shaking table test and multi-dimensional isolation and mitigation device are introduced briefly in this paper,then shaking table test is simulated by finite element program and the finite element results are compared with the experimental data , include natural frequencies , acceleration and inter-story displacement responses , which proves the finite element is right . On that basis , a parametric optimization modal is developed and the genetic algorithms method is used to complete the parametric optimization of multi-dimensional isolation and mitigation device , then dynamic responses of structure are compared with optimal parameter and sub-optimal parameter . The results show that horizontal acceleration , horizontal displacement and vertical acceleration of building structure reduce obviously after optimization analysis .
