摘要

对水平-竖向耦合地震作用下滑移隔震结构模型理论进行研究,建立其运动微分方程和滑移隔震结构参数优化设计模型。针对滑移隔震结构的特点,提出标准遗传算法的改进措施,并采用直接搜索算法与遗传算法相结合构成改进混合遗传算法。采用改进混合遗传算法对6层滑移隔震结构进行参数优化设计,可以很好地分析竖向地震作用对隔震层的影响。表明优化设计模型与优化设计算法对于滑移隔震结构的参数优化是有效的。
In order to study the influence of the action of coupling earthquake in both horizontal and vertical direction to vibration control structure and improve the effect of shock absorption of sliding base-isolated structure,theory of sliding base-isolated structure under the action of earthquake in both horizontal and vertical direction is researched.A kinematic differential equation is also developed accordingly.The optimal model for sliding base-isolated structure is set up.In view of the characteristics of parameters optimization of sliding base-isolated structure,the improvement measures of standard genetic algorithm are put forward.A new direct search algorithm is proposed and combined with improved genetic algorithm,which formed improved hybrid genetic algorithm.The parameters of 6-story sliding base-isolated structure are optimized with improved hybrid genetic algorithm and the influence of the action of earthquake in vertical direction is improved effectively.The results by exemplification show that the optimal model and improved hybrid genetic algorithm are efficient for parameters optimization of sliding base-isolated structure.
