Abstract EN
Taking advantage of the structural health monitoring system installed on the steel truss arch girder of Dashengguan Yangtze Bridge, the temperature field data and static strain data are collected and analyzed for the static performance assessment of the bridge.
Through analysis, it is found that the static strain changes are mainly caused by temperature field (temperature and temperature difference) and train.
After the train-induced static strains are removed, the correlation between the remaining static strains and the temperature field shows apparent linear characteristics, which can be mathematically modeled for the description of static performance.
Therefore, multivariate linear regression function combined with principal component analysis is introduced to mathematically model the correlation.
Furthermore, the residual static strains of mathematical model are adopted as assessment indicator and three kinds of degradation regulations of static performance are obtained after simulation of the residual static strains.
Finally, it is concluded that the static performance of Dashengguan Yangtze Bridge was in a good condition during that period.
