Optimum design parameters of tuned mass dampers are calculated as a function of damper to structure mass ratio and inherent damping ratio of the main structure in frequency domain. A robust control algorithm is adopted in order to assure response reduction in controlled structure subjected to different earthquakes, and an equivalent single degree-of-freedom structure is introduced to reduce the computation cost of optimum design. H ∞ norm minimization of this equivalent structure is considered as the objective function. Considering inherent structural damping for main structure, the recently developed metaheuristic algorithm known as CBO is used to find the optimum values of the design parameters. Using the proposed procedure, design charts are prepared for a 10-story shear building.

使用频域中碰撞体优化的调谐质量阻尼器的优化设计

调谐质量阻尼器的优化设计参数计算为阻尼器与结构质量比和主结构在频域中的固有阻尼比的函数。采用鲁棒控制算法保证受控结构在不同地震作用下的响应降低，并引入等效单自由度结构以降低优化设计的计算成本。该等效结构的 H ∞ 范数最小化被视为目标函数。考虑到主要结构的固有结构阻尼，最近开发的称为 CBO 的元启发式算法用于寻找设计参数的最佳值。使用建议的程序，为 10 层剪力建筑准备设计图表。
