전통 목조 건축물의 구조해석에 의한 안전성 평가

Evaluation of Safety by Structural Analysis of Traditional Wooden Building

본 논문에서는 전통 목조 건축물의 보다 실제에 가까운 구조특성을 파악하고 건물에 대한 안전성을 평가하기 위하여 현존하는 대표적인 전통 목조 건축물인 부석사 무량수전을 대상으로 하여 최대한 실제와 유사한 거동상태가 되도록 건축물을 3차원 및 2차원으로 모델링하여 범용 구조해석 프로그램을 통한 구조해석을 실시한 후에 해석결과를 비교, 분석하고 검토하였다.

In order to grasp and evaluate the characteristics and the safety of traditional wooden building, we select one of the representative traditional wooden building, Buseoksa Muryangsujeon in this study. After the two and three-dimensional structural analysis of this building are performed, the results are compared and analyzed. Following main conclusion are obtained: 1) By comparison between the results of two and three-dimensional structural analysis, they show that the exterior members of this building tend to transfer more load in the three-dimensional analysis. 2) The result of three-dimensional structural analysis shows that the every member stress of Buseoksa Muryangsujeon except Chobang and Jangyon is below allowable stress. 3) For exact modelling of joints of members in traditional wooden building such as Gongpo, it is necessary to accumulate and analyze the technical data through structural test and systematic analysis study.
