Prestress Loss and Uncertainty in Concrete Box Girder Creep
Original language description
The paper is directed to the cross section warping effect and to the warping induced long term prestress loss due to creep of concrete, which is analyzed deterministically and stochastically. The statistical variability of material creep parameters and environmental factors has a significant effect on the statistical scatter of the calculated prestress loss. In order to obtain the real development of concrete creep it is important to use a model with strong theoretical basis. Sophisticated model B4 provides very accurate concrete creep and shrinkage prediction. The statistical randomness of boundary and environmental conditions is solved by application of Monte Carlo – Latin hypercube sampling method. It is shown that the severity of cross section warping can be of fundamental importance, particularly in the case of unevenly distributed and isolated tendons in cross-section and in the case of short spans. Both the 3D effects and the statistical variability of creep must be taken into account if a reliable design of box girder bridges from the viewpoint of long-term serviceability should be achieved.
