Abstract

Lee, C.-E., Kim, G. and Kim, S. U., 2013. Stochastic reliability analysis of armor units of rubble-mound breakwaters under the multiple loads.

A stochastic reliability analysis model was developed for evaluating the time-dependent capacity variation of armor units of rubble-mound breakwaters subject to the multiple loads of arbitrary magnitudes which could occur randomly. The initial structural capacities and the damage rates of armor units of ruble-mound breakwaters was estimated as a function of the incident wave height with a given return period by using the modified Hudson's formula and Melby's formula. The structural capacity of armor units of rubble-mound breakwaters was also analyzed in detail through the lifetime reliability investigations according to the limit states such as the serviceability or ultimate limit state and the conditions of multiple loads. Finally, the repair intervals for the structural management was quantitatively evaluated by the present model that were developed by combining the target probability for repair and the accumulated probabilities of failure obtained from the present stochastic reliability analysis model.
