. Therefore, the traditional support methods can no longer meet the support requirements and a new high strength support technology is necessary. In ground structural engineering, confined concrete (CC) has...] carried out numerous slender short column bias tests of normal and high-strength concrete. The influence of high strength concrete on the overall bearing capacity and ductility of confined concrete......
