| 요약 | Owing to the country’s mountainous terrain, large-scale forest fires are continually reported, particularly along the East Coast. However, as forest areas expand on the West Coast, the prevalence of these incidents is increasing nationwide. This study assesses the impact of forest fires on check dams in mountainous regions, focusing on open dams composed of steel, GFRP, and CFRP. Using the commercial finite element analysis program ABAQUS, we observed that steel structures failed at approximately 600°C, whereas FRP structures remained intact even at temperatures exceeding 800°C. FRP materials exhibited stress levels 10.30%–11.20% lower than those of steel, with maximum displacements increasing by about 73.1 and 17.9 times. In concrete dams, stress concentration was noted at the connections with structural materials. Although the compressive side remained intact for all materials, tensile failure in the concrete occurred at temperatures above 600°C. Connections between dam bodies and structures using GFRP and GFRP showed reductions in reaction forces by 82.43% and 67.63%, respectively, compared with steel. These findings indicate that although FRP materials provide considerable high-temperature resistance, further research is essential to confirm these results, given their reliance on numerical analysis. |
