Abstract: Recognizing that the freeze-thaw damage is unevenly distributed on the component section, this paper proposed a concrete model that could take the uneven strength degradation due to freeze-thaw cycles into consideration, and a calculation method for equivalent numbers of freeze-thaw cycles was put forward. The model was validated using the data of pseudo static test on the reinforced concrete columns with different freeze-thaw damages. An existing concrete model concerning freeze-thaw cycles was also referred to make a comparison. The results show that the bearing capacity calculated by the proposed model is relatively conservative, and matches the test data better than the existing model which doesn’t consider the distribution of freeze-thaw damage, indicating that the proposed model could be used for modelling the seismic behavior of reinforced concrete columns with different freeze-thaw damage.

Key words: freeze-thaw cycles, reinforced concrete column, fiber section, concrete model, equivalent numbers of freeze-thaw cycles
