Abstract
잔교식 안벽구조물의 확률론적 지진위험도 해석을 수행하였다. 부지응답해석을 통해 증폭된 지표 지진이 구조물에 가해질 때 강관파일의 조합응력비와 최대수평변위가 한계상태를 초과하는 확률을 지진취약도 곡선으로 표현하였다. 해당 지역의 지진발생확률은 항만설계기준의 지진재해도를 이용하여 최대지반가속도의 초과확률을 구할 수 있었다. 구조물의 최종적인 지진위험도는 지진취약도와 지진재해도를 이용하여 산정하였으며 수치해석 예제를 통해 그 결과를 제시하였다.

Probabilistic seismic risk analysis was performed. Exceeding probabilities of combined stress and maximum horizontal displacement of steel piled pier due to surface ground motion which was transferred from base rock motion was expressed as seismic fragility curves. Occurrence probability of peak ground motion was calculated by using the seismic hazard map on design code for harbor and fishery structures of Korea. Finally seismic risk of pier structure was found by combining the fragility and the hazard and those were presented through numerical analysis.
