How long is the appropriate storage period for highway precast bridge beams? Graphic and textual analysis
The calculation results show that the deformation (arch) of the beam increases with the increase of the beam storage period, which means that the longer the beam storage period, the greater the deformation of the T-beam.
The maximum difference is the end span beam, and the differences are T-beam (360 days -30 days)=54.
4-42.
1=12.
3 (mm); Box girder (360 days to 30 days)=40.
0-32.
8=7.
2 (mm).
