ABSTRACT

In this paper, a smart optimized control technique is proposed. Structures are modelled using a coupled finite element method (FEM) and boundary element method (BEM), where building floors are modeled using BEM, and vertical elements are modeled using FEM without lumping of masses. Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) are combined to find the best configuration for MR dampers within a given structure and determine values of the performance function weighting matrices, respectively. Effective evaluation criteria are carried out against benchmark earthquakes. The proposed semi-active controller is compared with an ideal active and passive ON/OFF control systems.

摘要

本文提出了一种智能优化控制技术。使用耦合有限元法 (FEM) 和边界元法 (BEM) 对结构进行建模，其中建筑物楼层使用 BEM 建模，垂直单元使用 FEM 建模，无需集中质量。遗传算法 (GA) 和粒子群优化 (PSO) 相结合，以找到给定结构内 MR 阻尼器的最佳配置，并分别确定性能函数加权矩阵的值。针对基准地震执行有效的评估标准。将所提出的半主动控制器与理想的主动和被动开/关控制系统进行了比较。
