The Cause Analysis of Cracks on Key Segment of Box Girder of Fuli-Taoyuan Bridge
Publication: International Conference on Transportation Engineering 2007
Abstract
Cracks occur at the bottom of box girder on key segment of Fuli-Taoyuan bridge when tensioning the prestressing wire inside bottom slab by survey and calculation, it can be inferred that the down force under prestressing load is greater than theoretical value. The detail analysis of box girder under actually load reveals that concrete between prestressing wire holes is broken by down force, so cracks occur and propagate. In this paper, the advice of preventing such cracks is proposed.
