목조 건축 문화유산 손상 진단 정량화에 관한 기초 연구

This study develops a quantitative framework for assessing damage in wooden architectural heritage by proposing a damage mapping system and evaluation method. Research materials included an outdoor experimental model in Wanju, Jeollabuk-do, and three national survey reports published in 2022 by the Cultural Heritage Administration and the National Research Institute of Cultural Heritage. The experimental model was used to identify early-stage damage patterns, while the reports provided insights into long-term and complex deterioration. Based on these sources, a damage map was created incorporating wood-specific categories, such as insect damage and decay. Quantitative evaluation was conducted by overlaying grid units to calculate damage ratios. Among the grid sizes tested, 50 mm, 10 mm, and 5 mm, the 10 mm unit proved most effective, balancing accuracy and efficiency. Application to Geungnakbojeon Hall of Muwisa Temple in Gangjin confirmed the method’s practical validity, showing only a 0.46 percent deviation compared to measured data. This approach complements conventional survey methods, which often rely on subjective judgment, by providing a more objective and applicable system for the conservation and management of wooden heritage.
