Damage Analysis of Freeze-Thaw Processes in Hydraulic Structure Concrete

Abstract:

Based on the theory of damage finite element method, the deterioration process of hydraulic concrete under the freeze-thaw cycles is simulated. The damage evolution equation is deduced and freeze-thaw zone is discussed. The results indicate that the load capacity of structure is degraded under the freeze-thaw cycles. The deterioration of hydraulic concrete under the freeze-thaw cycles, however, is mainly limited at the region of the water fluctuation district and has a little effect to the overall structure. This means that the major loads causing hydraulic concrete failure under the freezing-thawing damage in the coldest region is not those of general design loads, such as gravity load and water pressure load, but the thermal loads, especially by the distinct daily temperature difference. Thus, the freeze-thaw modeling should consider these loads together.
