【摘要】 首先推导了随机输入下单个附属结构和多个附属结构的动力响应表达式,以此进一步分析了影响附属结构最优位置的各个因素,并提出了利用遗传算法进行附属结构位置优化的方法。最后用一个10层剪切结构作为算例,利用遗传算法并采用权重系数变换法进行了多个附属结构的多目标位置优化。更多还原

【Abstract】 The seismic response expressions of a single secondary system and a multi-secondary system with random input are derived.Based on these expressions,the optimal position of secondary systems gained using genetic algorithm is discussed.A 10-storey shear structure is selected as an example.Multi-objective optimization of a multi-secondary system is carried out with the genetic algorithm and the weighted coefficient method.更多还原
