| Abstract: |
In this paper, a simplified probabilistic analysis approach is presented. The Barqueiro Bridge, a four- span riveted iron bridge located in Galicia, Spain, is selected as a case study. This bridge is placed in an environment with high humidity and salinity which could potentially induce severe damages to the structure. These damages introduce considerable uncertainty in the structural parameters that should be used in reliability-based assessment procedures for verifying current safety conditions. To alleviate this issue, non-destructive experimental testing is used which also helps during numerical modeling. Model uncertain parameters are described through adequate probability distributions and then grouped by using two different strategies; based on structural element type and on stress level. According to this strategy, the limit state of interest is analyzed to verify the probability of failure and the reliability index of the structure. |
