A revised the B3 Creep Prediction Model Based on Short-Time Tests

The calculation of structure creep effect depends on the computational accuracy of concrete prediction model. Eight groups of test data were collected and used to evaluate six different prediction models. The differences between the calculated and the test data were analyzed. Based on the analysis, the method to improve the B3 prediction model was discussed, and the examples of revised B3 prediction model by the use of short-time tests were also presented. The results show that updating the prediction model based on short-time tests can improve the accuracy of B3 creep prediction model.
