摘要：
To study the reinforced concrete beam stress performance under ultra-low temperature, Monotonic static load tests of 6 reinforced concrete beams were conducted at a temperature range from -180 degrees C to -40 degrees C by using home-made jig and fixture for low temperature. The failure modes and the mechanical properties of the reinforced concrete beams under low temperature were investigated. The test results showed that both the bearing capacity and the stiffness of the beams increased with the decrease of the temperature. Based on the material constitutive and mechanism at ultra-low temperature, the numerical simulations are implemented and component test is expanded by using DIANA software environment.
