Abstract

Calibration of load-resistance factors for the limit state design of front covered caisson breakwaters were presented. Reliability analysis of the breakwaters which are constructed in Korean coast 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, load-resistance factors were compared with foreign country's code for verification.

소파블록 피복제 제체의 한계상태설계법 개발을 위해 하중저항계수 보정을 수행하였다. 실제 시공된 소파블록 피복제 제체의 설계자료를 분석하여 신뢰성해석을 수행하였으며 목표신뢰성지수에 따른 부분안전계수와 하중, 저항계수를 차례로 산정하였다. 최적화기법을 통해 한계상태설계법 개발을 위한 하중계수와 저항계수를 도출하였다. 최종 하중저항계수를 이용하여 방파제를 재설계하였으며 목표수준의 신뢰성지수를 상회하는지 검증하였다. 해외기준의 하중저항계수와 본 연구에서 구한 하중저항계수를 비교하였다.
