Abstract

For the study of reinforced concrete beam stress performance under ultra-low temperature, based on the material constitutive and mechanism at ultra-low temperature. The concrete constitute model and the simulation model are presented by DIANA software environment, the numerical simulations is implemented. The component test is expanded, and the experimental program is presented. The result of component test is compared with the simulation of DIANA. The results show that the reinforced concrete beam bearing capacity and stiffness are increased with lower temperature.
