And within the transportation networks, bridges are key elements for connecting people anddelivering goods.

World’s First Thermoplastic Bridges

Deterioration of bridges in the United States has been well recognized. According to the FHWA National Bridge Inventory, one third of nearly 600,000 U.S. highway bridges are classified as structurally deficient or functionally obsolete. Since the majority of bridges were built using wood, steel or concrete, the same conventional materials have been used for bridge replacement or rehabilitation,...

Passive Control of Bridges

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 sup...
