According to the non-uniform shrinkage phenomenon of the box girder section,the model experiment was made and different concrete mix proportions and nominal depths were considered.Based on the nonlinear moisture diffusion theory,a finite element model was established for the specimens.The test and theoretical analysis results show that the phenomenon of non-uniform shrinkage of box section is obvious and the differential shrinkage value between top and bottom of the section is 13% to 18% of the… CONTINUE READING
