Multi-objective optimisation of damper placement in dynamically similar adjacent buildings is considered with identical viscoelastic dampers used for vibration control. An 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 inter-storey 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.

多目标优化阻尼器位置，以改善动态相似的相邻建筑物的地震响应

考虑使用用于振动控制的相同粘弹性阻尼器，对动态相似的相邻建筑物中的阻尼器放置进行多目标优化。详尽搜索用于根据各种感兴趣的量来描述解决方案空间，例如最大的顶层位移，最大的楼层加速度，基础剪力和层间漂移。借助于示例，指出在这些问题中的帕累托前沿包含很少的解决方案。两种常用的多目标进化算法的有效性。针对特定示例评估了NSGA-II和MOPSO。
