Abstract
Pile supported wharf is a framed structure which supports the superstructure of RC with a steel pipe pile. Major damage mechanism of the wharf is the occurrence of the plastic hinge in the piles. As the close technical field survey is required for the evaluation of the damage level of the piles, it is difficult to judge the serviceability of the wharf just after the earthquake.
This study discusses the evaluation method of the degree of damage of pile supported wharf by earthquake focusing the natural period of the wharf. In this study, two dimensional finite element earthquake response analysis modeling pile supported wharf is conducted. As the result, natural period of the wharf becomes approximately 1.2 times longer when plastic hinge occurs in the pile.
