| Abstract: |
| Applicability of 3 kinds of prediction model in prediction of concrete creep was analyzed through comparison between calculation value and experiment data.And also B3 prediction model for creep was updated by changing some parameters of the model to enhance the accuracy of prediction.Finally some useful suggestions were made for the selection of creep prediction model in structural design and analysis. |
