Structural Design of Railway Structure with No Footing Beams

Abstract

We are studying design method of the railway structure with no footing beams in order to decrease excavations beside tracks, from a point of view of safety during neighboring construction works with railwaytracks. In this report, we introduce the design method of over-track buildings and of land bridges with no footing beams. On designing, we basically use statically elasto-plastic analysis with connecting models of columns and piles. We prescribe the order of yield mechanism occurrence, and that the column-pile joints do not yield.
