It has been recently proved for bridges that the collaboration between a deck structure and an external pre-stressed cable is a very advantageous structural system due to the fact that the use of external pre-stressing cables neutralizes the permanent loads. However, the action of the moving loads on the cables causes large displacements not compatible with the connected deck structure. A successful method to minimize the aforementioned undesirable displacements is to use a passive control system based on an a priori upward, vertical deformation of the deck due to the pre-stress action of the supported cables. In the present paper, a bridge model (of type MNB after Michalopoulos Nikolaidis Baniotopoulos) based on a concrete plate connected with steel beams is proposed and studied.
