Abstract This study examines the structural characteristics of Heejeongdang, a traditional timber building in Changdeokgung, and evaluated its performance through three-dimensional structural analysis. A structural model was created using midas Gen, and the safety and serviceability of key structural members were assessed according to Korean Design Standards. The roof load per unit projected area was 9.773 kN/m², which is relatively high compared to similar traditional timber buildings. Structural safety was assessed using stress ratios under critical load conditions. The maximum axial stress ratio in columns was 0.512, and the maximum combined stress ratio reached 0.595, indicating relatively high stress levels. The SangJoongdori Janghyeo, a major horizontal member, showed the highest flexural and shear stress ratios at 0.846 and 0.914, respectively, approaching allowable limits. These elevated values result from the large roof load, a limited number of columns, and long spans. Serviceability was evaluated based on long-term deflection and lateral drift. The maximum deflection ratio of 0.656 occurred at Daelyang7 in the central bay, while most members had ratios below 0.5. Maximum inter-story drift ratios under wind and seismic loads were 0.127 and 0.443, respectively, both within allowable limits.
