Determining structural properties of a prestressed concrete bridge through the combination of static and dynamic load testing

Eugen Brühwiler, Yves Sylvain Gilles Reuland, Numa Joy Bertola

Examining structural safety requires hypotheses on several properties of the bridge structure, such as material properties, boundary conditions, and self-weight. The traditional approach relies on conservative assumptions for each structural property, foll ...
