OPTIMAL ACTUATOR DESIGN FOR CONTROL OF VIBRATIONS INDUCED BY PEDESTRIAN-BRIDGE INTERACTIONS.

In this paper, we are interested in fnding an optimal control support design for controlling vibrations due to pedestrian-bridge interactions. Therefore, we derive the topological derivatives of the proposed functionals using the averaged adjoint approach. A numerical algorithm initialized by these sensitivities is used as a solution strategy. The algorithm is tested numerically for two different cases of initial conditions. [ABSTRACT FROM AUTHOR]
