Abstract

Vibration control of irregular structures subjected to earthquake excitations is a complex civil engineering problem. Base isolation has been used as an earthquake-protective system over the past few decades. It is, however, a passive control system lacking the adaptability to the real-time changes in motion from the earthquake excitation. In order to aid the base isolation system, control devices are installed at the base to provide the real-time vibration control. This research is motivated by evolutionary game theory and uses replicator dynamics as a resource allocation algorithm to determine control decisions. The control algorithm is evaluated using a three-dimensional base-isolated benchmark structure subjected to major historical earthquakes.
