This study evaluated the effect of eccentricity ratio according to plan types on the seismic performance of school buildings based on design drawings from the 1980s. The analytical models reflected school buildings constructed based on the standard design drawings of the 1980s, and the main variables were set as ┣┫, ━, ┏━, and ┏┛ plan types. Seismic performance was analyzed based on performance points, plastic hinge distribution, axial load sharing ratio, and inter-story drift ratio. The results showed that the ┣┫ and ━ type structures with low eccentricity ratios secured stable behavior and member performance at the IO level, whereas the ┏━ type structure with a high eccentricity ratio showed a tendency for seismic performance deterioration with collapse-level members concentrated on the first floor. In addition, the ┏┛ type structure exhibited collapse-level members despite a relatively low eccentricity ratio, and performance points were not formed in some directions, indicating insufficient seismic performance. Therefore, the eccentricity ratio according to plan type needs to be considered as a key factor in evaluating the stable seismic performance of school buildings. |
