Abstract
The objective of the present research is to show and to quantify the importance of soil parameter uncertainties on the redistribution of internal forces in RC bridges, as well as their effect on the safety assessment of these structures. In this paper, a reliability-mechanical approach was developed to study the effect of soil-structure interaction for RC bridges. The modeling of soil-structure interaction is incorporated in the mechanical model of RC continuous beam, by considering nonlinear elastic supports. The deterministic and reliability analysis allows us to evaluate the safety of the RC bridge regarding the soil parameter uncertainties. The numerical analysis allows us to evaluate the safety of the RC bridge regarding the soil parameter uncertainties. Furthermore, the obtained results indicate that soil–structure interaction effects and uncertainty of soil parameters should be considered in the reliability assessment of RC structures. This analysis can have significant impact on the design rules of redundant RC structures, especially when large soil uncertainties are involved.
