Seismic Design ground motion standards changed due to recent earthquake damage become large, and the railway seismic resistance standard has an elastic response of up to 2.6 G. This makes the structure large. In particular, pile diameter, pile length and reinforcing bar amount increase in underground. To address this issue, we are investigating a rational damage-preventing connection method for pile structures with the aim of reducing the performance and cost of piles. In this paper, we present an analysis of the analysis.
