Abstract: The short-term elastic and long-term time-dependent behavior of extradosed bridges with composite girders are studied. Analysis is carried out with a FEM step-by-step method, which was developed originally at Yamaguchi University. It is confirmed that large changes of the deflection and the longitudinal stress distribution occur and the stresses in the concrete slab increase in compression for a long period.
