Abstract
The roof in Korean traditional wooden architectural building makes the greatest impact on forming the shape of the facade and its eaves curve and inner west are evaluated as the most beautiful and important design elements of the Korean traditional architectural building due to their elegant curves along with their visual correction function for the heavy roof. In addition, the eaves curve in East Asian wooden architecture built with similar ingredients and structures serves as a criterion to distinguish the localities and features a variety of forms with the personalities of architects incorporated in it. This study has analyzed the characteristics of eaves curve based on the elements significantly correlated with the eaves curve through correlation analysis and the results are as follows. First, the eaves curvature diagram tends to be inversely proportional to the size of lateral toekan. Second, the lateral straight line section was shortened if the ratio of lateral jeongkan was large. All in all, the lateral roof curves were formed by intentionally adjusting the eaves curvature diagram according to the ratio between the lateral jeongkan and toekan.
