Research on dynamic compressive failure criterion of concrete at high temperature

By using the SHPB device, uniaxial impact compression test of concrete were carried out at different temperature (20 degrees C to 650 degrees C). The strength data of concrete at different temperatures and different stain rates was obtained and uniaxial compressive failure criteria of concrete were obtained, in which the high temperature and the strain rate were considered, and it would provide reference for actual projects.
