提出以能量和控制效果指标为目标函数的黏滞阻尼器优化设计方法。基于黏滞阻尼器参数对其滞回曲线的影响，在分别以加速度控制效果指标和能量为目标函数的情况下，采用遗传算法对黏滞阻尼器进行了布置及参数的同步优化，在综合考虑了位移控制效果指标、加速度控制效果指标及能量的情况下，再次对黏滞阻尼器进行了优化设计，将三种黏滞阻尼器优化设计结果与传统设计结果进行了比较，并分析了四种阻尼器设计结果对地震的敏感性。研究表明：考虑能量的黏滞阻尼器优化设计是有效的，在目标函数中引入能量可以减小设计结果对地震波的敏感性。

英文摘要：

It was proposed a viscous damper optimization design method, in which energy and control effect indexes were used as the objective function. Based on the effect of viscous damper parameters on the hysteresis curves, in the cases of using acceleration control effect index and energy as the objective function respectively, the genetic algorithm was used to optimize the the layout and parameters of viscous damper synchronously, in the case of considering displacement control index, acceleration control effect index and energy comprehensively, it was optimized viscous damper again. Three viscous damper optimization design results were compared with traditional design result, and the sensitivity of four damper design results to earthquake waves was analyzed. Research shows that the viscous damper optimization design which considers energy is effective, introducing the energy in the objective function can reduce the sensitivity of design results to earthquake waves.
