Abstract:
The mechanical property of the PC box girder bridge with transverse cracks occurring in the midspan area is complex, and the evaluation of the bearing capacity is difficult. Based on the statistic parameter of cracks, through converting the real transverse cracks into the statistic average ones, these statistic cracks are simulated with the numerical analysis method. After comparing the analysis results of the uncracked bridge with the ones of the cracked bridge, the variation of the bearing capacity can be estimated. The results show that the bearing capacity of the PC box girder structure with transverse cracks is 80% of the one of original design. 2 tabs, 8 figs, 10 refs.
