Resum
This paper presents an externally prestressed high strength concrete viaduct designed and erected in Spain. This viaduct, a three-span (41 + 50 + 41 m) continuous beam, has been designed and built with a 60-MPa strength concrete and a fully external replaceable prestressing. The paper describes the bridge, the erection procedure, the ultimate analysis performed with a nonlinear finite-element numerical model, and the thermal stresses measured and calculated at the anchorage diaphragms due to the...
