Abstract:
In the design of bridges with large spans, the significant values of the moments at the main deck-structure
require very heavy members, either in the case of a beam or a truss deck-structure. 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 method.
