This paper aims at discussing the reliability indices for the members of jacket type wharves designed by conventional design method. First-Order Reliability Method was used for the calculation of the reliability indices for conditions under level-one earthquake ground motion, berthing and traction.
The results of the analyses indicate that the reliability indices for the members of jacket type wharves have larger dispersion than those of the pile-supported wharves. For conditions under level-one earthquake ground motion, the average reliability indices of can, brace and upper-pile are larger than those of pile at undersea and lower-pile. Reliability indices for the latter are less than those for pile supported wharves. For conditions under berthing and traction, the reliability indices are almost the same level as those for the pile-supported wharves.
