Abstract

This study developed a three-dimensional structural analysis model of the middle gate of eastern-western precincts at the Mireuksa temple site and evaluated its structural performance using Midas Gen. Safety was assessed based on stress ratios under critical load combinations, while serviceability was assessed based on deflection and lateral displacement. The maximum axial and combined stress ratios of the columns were 0.097 and 0.261, respectively, thus indicating adequate safety margins. However, the lower Majbo (a transverse tie beam) and rafters exceeded the allowable stress limits by 95.3% and 121.8%, respectively, and the deflection limits by 23.9% and 70.4%, respectively. The X-direction seismic drift exceeded the allowable limit by 19.5%. These results indicate that some members require redesign and strengthening, thus highlighting the necessity to verify historical dimensions against structural performance in restoration design.

본 연구에서는 미륵사지 동･서원 중문의 복원 기본설계를 바탕으로 Midas Gen을 이용하여 구조성능을 정량적으로 평가하였다. 안전성은 위험하중조합에 대한 응력비로, 사용성은 처짐 및 횡변위로 검토하였다. 해석 결과, 기둥의 최대 축응력비와 조합응력비는 각각 0.097과 0.261로 안전여유가 충분하나, 맞보(하)와 서까래는 허용응력 기준 대비 각각 95.3%와 121.8%를 초과하였다. 처짐 또한 맞보(하)와 서까래에서 기준 대비 각각 23.9%와 70.4% 초과하였으며, X방향 지진하중에 대한 횡변위는 기준 대비 19.5% 초과하였다. 이로부터 일부 부재에 대한 단면 재산정 및 구조보강이 필요하며, 전통건축 복원 설계 과정에서 고증 치수와 구조성능 간의 정량적 검토의 필요성을 확인하였다.
