RELATION BETWEEN SAFETY INDEX AND SENSITIVITY FACTOR FOR STABILITY OF CAISSON-TYPE BREAKWATERS

Abstract

It is important to specify most dominant design parameters affecting safety of structures and to improve estimated accuracy of them in order to promote construction cost reduction through the reliability-based design. In this study, the dominant parameters for stability against sliding, overturning, and foundation failure of caisson-type breakwaters are specified by using safety index and sensitivity factor with FORM (First-Order Reliability Method). Moreover, correlations among failure modes in present design sections were described.
