Περίληψη

In the design of bridges with large spans, the significant values of the moments at the main deck-structurerequire very heavy members, either in the case of a beam or a truss deck-structure. In order to minimize theinfluence of bending moments, several applications of passive control of displacements using cable nets areherein proposed. The base for all the proposed systems is the cables supported beam nets with additionalprestressing control on support cables to optimize the structural behavior of the system. The passive controldesign problem leads to an optimal control problem for structures governed by variational inequalities. In thispresentation several bridge systems are proposed and studied as applications of this method
