A Study on Limit Deformation to Out-of-Plan Direction of Wall with Internal Structural Element in Traditional Wooden Walls

전통목구조 중깃 사용벽체의 면외방향 한계변형에 관한 연구

A study was conducted to determine the limit drift ratio of a traditional wooden structure wall. One of the national treasure traditional wooden buildings, the deformation is proceeding from the right side wall of Muyangsujeon to the out-of-plane direction. By this reason, the limit drift ratio was determined by selecting the wall of Muyangsujeon as an example of this study. Although there is a limitation that the Muyangsujeon wall does not mean all walls of the traditional wooden structures, the purpose was to provide basic data to choice a reasonable determination in the case of a Traditional Wall constructed in a similar way to the Muyangsujeon wall. In the case of historical buildings, it is often difficult to know exactly what is needed, so this study tried to determine the limit drift ratio of a traditional wall by using the minimum information available such as wall deformation and wall size. It has been confirmed that in the case of a traditional wall with studs inside, such as the right wall of Muyangsujeon wall, an unstable condition may occur when the limit drift ratio of the point in the center of the wall divided by the height of the wall divided by the wall height approaches 3.1%.
