In case of stone pagoda structures, the various construction types appear, and various damages occur due to exposure to the outdoors for a long time. Such damages can be classified into non-structural damages and structural damages. However, studies for the effects of structural damages on stone pagoda structures are insufficient. Accordingly, this study intends to perform structural modeling and structural analysis according to structural damages of stone pagoda structure, and to perform risk analysis through the fragility curve. So, we expects that this study gives a great contribution to the preservation and maintenance of stone pagoda structures under the various structural damages.

The Gyeongju and Pohang earthquakes caused damages to many cultural properties; particularly, stone pagoda structures were significantly damaged among masonry cultural properties. To preserve these structures, it is necessary to understand their dynamic behavior characteristics under earthquakes. Analyses on such areas as deformation, frequency, maximum acceleration, permanent displacement, sliding, and rocking have to be performed. Although many analytical studies have already been conducted, dynamic behavior studies based on experiments are insufficient. Therefore, this study analyzed dynamic behavior characteristics by performing a shaking table experiment on a three-story stone pagoda structure at the Cheollongsa temple site damaged by the Gyeongju earthquake. As a result of the experiment, the displacements of stylobates did not occur significantly, but the tower body parts rotated. In particular, the rotation of the 1F main body stone was relatively larger than that of the other chief body stones because the 1F main body stone is relatively more slender than the other parts. In addition, the decorative top was identified as the component most vulnerable to sliding. This study found that the 1F main body stone is vulnerable to rocking, and the parts located on the upper part are more vulnerable to sliding.

석탑문화재는 오랜기간 야외에 노출됨으로써 자연재해, 인위적 훼손 등으로 인해 다양한 손상이 발생하고 있다. 이러한 다양한 손상유형에 따른 구조적 안전성을 확보하기 위해서는 체계적인 손상유형의 분류와 손상요인에 대한 분석이 필요하다. 이에 따라 본 연구에서는 석탑문화재에 발생하는 다양한 손상을 구조적 손상과 비구조적 손상으로 분류하고 손상유형에 따른 구조적 영향요인을 분석하고자 한다.

설비배관은 온도에 의한 신축 및 팽창을 고려한 설계를 하거나, 배관의 자중만을 고려하여 설계되고 제작된다. 그러나 설비배관 행거시스템에 지진 또는 지속적인 외부 진동이 발생하면 그 충격을 감소 및 흡수하지 못하고 2차적인 피해로 이어질 수 있다. 이에 따라 본 연구에서는 내진성능을 고려한 설비배관 행거시스템을 개발하고, 진동대 실험을 통해 지진거동특성을 평가하고자한다.
