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 blend into the environment. A disadvantage of the classical stress-ribbon 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, two new self anchored structural systems that combine the stress-ribbon with the arches have been developed. In the first one the stress ribbon is supported by an arch, the second one combines a curved stress ribbon with a curved flat arch.
