Multi-objective optimisation of damper placement in dynamically symmetric adjacent buildings is considered with identical viscoelastic dampers used for vibration control. First, exhaustive search is used to describe the solution space in terms of various quantities of interest such as maximum top floor displacement, maximum floor acceleration, base shear, and interstorey drift. With the help of examples, it is pointed out that the Pareto fronts in these problems contain a very small number of solutions. The effectiveness of two commonly used multi-objective evolutionary algorithms, viz., NSGA-II and MOPSO, is evaluated for a specific example.

阻尼器放置的多目标优化以改善动态相似相邻建筑物的地震响应

动态对称相邻建筑物中阻尼器放置的多目标优化被考虑使用用于振动控制的相同粘弹性阻尼器。首先，穷举搜索用于根据各种感兴趣的量来描述解空间，例如最大顶楼位移、最大楼板加速度、底部剪切和层间漂移。借助实例，指出这些问题的帕累托前沿包含极少数的解。两种常用的多目标进化算法（即 NSGA-II 和 MOPSO）的有效性通过一个具体的例子进行评估。
