| 摘要： | This report presents the analysis and results from the study of the time-dependent behavior of an actual pre-stressed concrete bridge as determined from field measurement of strains and temperature at various locations in the bridge structure. It further discusses the resulting pre-stress losses from creep and shrinkage of concrete, as well as, their effects on stress re-distribution in the bridge girders, and on camber and deflection of the girders. The bridge instrumentation techniques used and preliminary results from this bridge were subject of Phase I of this study which was presented in a previous FDCT report titled “Field Measurement and Evaluation of Time-Dependent Losses in Pre-stressed Concrete Bridges”. |
