Abstract

Two variations of bio-inspired, population-based optimization frameworks are proposed to optimize damper distributions in structures subjected to earthquakes. In the first approach a predefined number of records are randomly selected and assigned to each individual of the population. The second approach consists of clustering individuals with similar characteristics, and
each individual of each cluster is subjected to just a few randomly selected ground motions.
The proposed variations are applied to an archetype building model subjected to different sets
of ground motions caused by different types of earthquakes (shallow crustal and subduction).
It was found that the clustering approach is much more convenient in the sense that it reduces
the computational cost without significantly affecting the quality of the solution.
