A STUDY ON THE STABILITY DESIGN OF TOWER OF CABLE SUPPORTED BRIDGES

Abstract

Recently in Japan, there has been a marked tendency toward longer spans in cable supported bridges (suspension bridges and cable stayedbridges). However, towers have been designed in accordance with each public corpolation's own code, and common standards for tower design methods have yet been established. Therefore, we conducted an investigation into stability design procedures of towers for long-span bridges in Japan. We could obtain useful results, clarifying the characteristics and practical problems of the standing codes regarding towers. We believe that it will be possible to use these results in order to establish a new design procedure in the future.
