Refined and Dractical Analysis of Main Cable Shape of Self-anchored Suspension Bridges
摘要
Abstract
To calculation the main cable shape of self-anchored suspension bridges,this study proposes a segmented catenary theory based on the traditional calculation method,that satisfies the laws of conservation of mass with-out solving nonlinear equations.Based on this theory,a program SASB_1 was compiled to calculate the main cable shape and stress-free length under the designed dead load condition of self-anchored suspension bridg-es.The reliability and accuracy of the algorithm were verified through classic calculation analytical case and model tests conducted on the Taohuayu Yellow River Bridge in Henan Province.关键词
