| Abstract: | Diverse polynomial functions were adopted to describe temperature distribution of cable-stayed bridge combined with measured temperature.Based on the test results,the theoretical analysis method of temperature influence was researched specially for cable-stayed bridge.According to the characteristics of front-supported frame,a whole technique to eliminate temperature influence was developed,which is real-time,and very suitable to field analysis and accords with parameters estimation and prediction.After verified by construction control of a real bridge,it is very successful and can be used to correct temperature influence of concrete cable-stayed bridges in field. |
