| Abstract: | It was investigated the variance rule of elastic model aftercontrol plain concrete and antifreezing admixture concrete at minus-temperature frost. The freezing damage mechanics equation and its damage fractor ω of concrete at minus-temperature are determined.And then some value of allow damage factor ωz in engineering structure are shown.This work is foundation of research for the design of engineering structure and damage mechanics and reduce calamity technology of concrete at minus-temperature. |
