Original Abstract

Stress-ribbon bridges consist of very slender concrete deck segments placed over bearing cables in the shape of a catenary. These bridges are characterized by successive and complementary smooth curves that blent into the environment and clearly articulate the flow of internal forces. The structures have minimal environmental impact because they can be erected without falsework. A disadvantage of the classical stress-ribon type structure is the need to resist very large horizontal forces at the abutments, which determines the economy of that solution in many cases. For that reason, new systems that combine the stress-ribbon with the arches or cables have been developed. Recent development has also proved that the stress ribbon structures can have cranked alignment and can be designed in a plan curvature.
