Surrogate-based dimension reduction for reliability analysis and LRFD calibration: Breakwater foundations in depth-varying soils

Key Points

• Reliability analysis indicates significant improvements in LRFD calibration accuracy with surrogate-based approaches.
• Key evidence shows a reduction in computational time by approximately 40% for assessing breakwater foundations.
• Assessment using surrogate-based dimension reduction techniques offers enhanced efficiency in reliability analysis.
• Highlights the need for further validation in real-world applications, especially in varying soil conditions.
