ABSTRACT
ABSTRACT It is necessary to conduct two-dimensional nonlinear earthquake response analysis many times in order to evaluate probabilistic characteristic of residual deformations and maximum bending moment of a pile supported wharf by earthquake. This paper aims at proposing a simple estimation method for those parameters of pile supported wharf. Variations of input earthquake ground motion were evaluated based on the variations of site amplification factors. It was shown that the probability distributions of residual deformations and maximum bending moment of a pile supported wharf can be evaluated with enough accuracy by using the result of three earthquake response analyses.
