| Abstract: | Based on the study of temperature and stress changes in basement exterior concrete wall in 14 days, the relationship between interior and exterior restraints in this kind of structure is analyzed. Considering the effect of temperature history on shrinkage compensation rate, this article gives a new simulation method for analyzing the shrinkage compensation concrete (SCC) wall stress, which is verified by a project at last. This calculation model will be more accurate in SCC wall project design than conventional methods. |

| Keywords: | shrinkage compensation concrete (SCC) side wall temperature history simulation |
