Abstract

In this paper, the structural performance of Suwon Hwaryeongjeon Unhangak, a representative traditional timber structure in the late Joseon Dynasty, was evaluated. Based on the structure composition of Unhangak, an analysis model was elaborately constructed with Midas Gen, a 3-dimensional structural analysis software. The safety and serviceability of major structural members were evaluated by static analysis, and the dynamic behavior characteristics were evaluated by eigenvalue analysis. Most of the members satisfied the safety and serviceability standards with a margin; however, the bending stress ratio in the oemogdori exceeds the standard by 20.7%, so it is considered that long-term monitoring is needed for this member. The natural period of Unhangak is 1.079 seconds, which is slightly longer than traditional timber buildings of similar scale. In particular, it is analyzed that torsional movement occurred in the secondary mode due to the influence of the rear masonry firewall.

본 논문에서는 조선 후기의 대표적인 전통목구조인 수원 화령전 운한각의 구조성능을 평가하였다. 운한각의 가구구성 방식에 맞추어 3차원 구조해석 소프트웨어인 midas Gen으로 해석모델을 정교하게 구축하였다. 정적해석으로 주요 구조부재의 안전성과 사용성을 평가하였고, 고유치해석으로 동적거동특성을 평가하였다. 대부분의 부재가 안전성 및 사용성 기준을 여유 있게 만족하고 있으나, 외목도리에서 휨응력비가 기준을 20.7% 초과하고 있어 이 부재에 대해서는 장기적인 모니터링이 필요하다고 사료된다. 운한각의 고유주기는 1.079초로 비슷한 규모의 전통목구조보다 약간 긴 편이며, 특히 후면 화방벽의 영향으로 2차모드에서 비틀림이 발생한 것으로 분석된다.
