The purpose is to investigate the effects of the pile section selection to the seismic performance, the effect of location of plastic hinges to the overall behavior of structure and the use of nonlinear pushover analysis to refine the pile section. Three sets of pile class as classified by Eurocode EN 1993-1-1 have been studied. The results reveal that the pile design with in-ground plastic hinges using sections class 1 or 2 is an economical option, especially for strong ground motions, using sections class 3 or 4 leads to uneconomical design for strong ground motions, and that using pushover analysis enables specifying sections class 1 or 2 for some piles and class 3 or 4 for others in each pile bent of wharf. The latter case offers economic benefits when some piles have high axial demand but remain otherwise elastic.
