초록

유공케이슨 방파제의 한계상태설계법 개발을 위해 하중저항계수 보정을 수행하였다. 전국 항만의 12개 유공케이슨식 방파제에 대하여 설계변수의 불확실성을 고려한 신뢰성해석을 수행하였다. 목표신뢰성지수에 따른 부분 안전계수와 하중, 저항계수를 차례로 산정하였다. 최적화기법을 통해 한계상태설계법 개발을 위한 하중계수와 저항계수를 도출하였다. 최종 하중저항계수를 이용하여 방파제를 재설계하였으며 목표수준의 신뢰성지수를 상회하는지 검증하였다. 목표신뢰성지수를 변화시켜 해당 수준에 맞는 하중저항계수를 최종 제시하였다.

Calibration of load-resistance factors for the limit state design of perforated caisson breakwaters are presented. Reliability analysis of 12 breakwaters in nationwide ports was conducted. Then, partial safety factors and load-resistance factors were sequentially calculated according to target reliability index. Load resistance factors were optimized to give one set of factor for limit state design of breakwater. The breakwaters were redesigned by using the optimal load resistance factor and verified whether reliability indices larger than the target value. Finally, some load-resistance factors were proposed by changing target reliability index.
