Long-term behavior of precast concrete girder with cast in place deck and diaphragm
Apstrakt
Composite precast-cast in place bridge girders made continuous for live load are very
popular solution for bridges of small to medium spans. In domain of service state of stresses,
material nonlinearity of concrete structures, manifested through creep, shrinkage and cracking,
plays an irnpmiant role in structural behavior. As for the design for long-term effects restrained
bending moment that would develop over intermediate supports is most critical feature. In order
to predict time-dependant effects in concrete structures, engineers need reliable data for creep
and shrinkage properties of concrete and analytical procedures to account for these effects.
There are several recommendations for time-dependant concrete prope1iies, and developments in
computational techniques make it possible to use any type of model. This study was undertaken
as an attempt to evaluate the influence of various creep and shrinkage model recomendations on
the continuity behavior of composite concrete... girders made continuous, after an extended period
of time.In this paper numerical simulation is obtained using nonlinear FEM model of DIANA
application.
