| Abstract: | linear regression model of relaxation test data for low relaxation PC strand has been established with mathematical statistics method, to be used for calculating 1 000 hours relaxation forecast value. On the basis of calculating, you can analyse and ascertain whether the specimens comply with the requirements of specification, and even assess the validity of test and the reliability of regression results. |
| Keywords: | ow relaxation PC strand relaxation test data linear regression model forecast value confidence interval |
