Comparative Analysis of Various Kinds Concrete Creep Prediction Models

The ratio of bridges to High-speed Railway line in China is very high. The influence of concrete creep to bridge structure is also very high, so it is necessary to study the creep of concrete in depth. In this thesis, experimental data of four important regions in China are collected and the curves of concrete creep are analyzed. By comparing the domestic and foreign curves of Concrete Creep Prediction Models, the difference between them could be found. In addition, the theory of long-term deformation of concrete obtained by a short-time experiment, which is proposed by Professor Bazant, is used. According to experimental data, the creep curves are fitted by a regression method. Finally, the comparison between common prediction models and Bazants’ theory is carried out and it can be found that the regression value is close to the measured value.
