In order to minimize the influence of bending moments, several applications of passive control of displacements using cable nets are herein proposed. The base for all the proposed systems is the cables supported beam nets with additional prestressing control on support cables to optimize the structural behavior of the system. The passive control design problem leads to an optimal control problem for structures governed by variational inequalities. In this presentation several bridge systems are proposed and studied as applications of this methodhttp://creativecommons.org/licenses/by/4.0/Jordan Journal of Civil Engineering 21173-185 Stavroulakis Georgios Σταυρουλακης Γεωργιος Michalopoulos Alexandros Μιχαλοπουλος Αλεξανδρος Nikolaïdis, Efthymios Baniotopoulos, C.C Applied mechanics Engineering, Mechanical mechanics applied applied mechanics engineering mechanical
