| Abstract |
This study evaluates the structural performance of Cheongpunggak, a replica of Soswaewon Gwangpunggak. Using midas Gen structural analysis software, the safety and serviceability of key structural members were assessed according to wooden structural design standards. Safety was measured by stress under critical load combinations. The maximum axial stress ratio for the columns is 0.106, indicating a significant margin. The maximum bending stress ratio for the main horizontal members is 0.518 at the Jusimdori, and the maximum shear stress ratio is 0.802 at the Jusimdori Janghyeo, both on the safe side. Serviceability was evaluated through deflection and story drift. The maximum deflection ratio for the main horizontal members is 0.326 at the side Jusimdori. The maximum story drift, evaluated for wind and seismic loads in both the X and Y directions, is 0.340 for wind loads and 0.570 for seismic loads, both within acceptable limits. Without walls, the story drift ratio increased by an average of 1.586 times, highlighting the walls' significant impact on lateral stiffness. |
