Abstract
Analysis is performed to evaluate the response and control energy dissipation in actively controlled elastic structures during earthquake. Previous studies show that using optimal control algorithm gives optimal control results only in terms of the selected cost function, but it may not be the most efficient when the results are compared to another choice of cost function. In view of this shortcoming, the present research uses maximum control energy dissipation to define the most effective optimal linear control law, and results show that maximum control energy dissipation exists and it depends highly on the earthquake characteristics.
