Load Resistance Factors Calibration for Limit State Design of Non-Perforated Caisson Breakwater

摘要

Load resistance factors for the limit state design of vertical caisson breakwaters are presented.Reliability analysis of 16 breakwaters in nationwide ports was conducted to calculate the partial safety factors and they were converted into load and resistance factors.The final load resistance factor was calibrated by applying the optimization technique to the individually calculated load resistance factors.Finally,the breakwater was redesigned using the optimal load resistance factor and verified whether the target level was met.The load resistance factor according to the change of the target reliability level is presented to facilitate the limit state design of breakwater.
