In many reasons of causing cracks, only a few studies are reported about the influence of concrete shrinkage and creep on cracks for its computational complexity. If any, most calculations are only based on the two-dimensioned finite element model. So it's significant that how to analyze the spatial effect of concrete shrinkage and creep by utilizing large software.
