摘要
Abstract
In order to understand the mechanical properties of the key parts of the irregular pylon of the urban cable-stayed bridge accurately,one certain 70 m+80 m+200 m+80 m+70 m cross-sea cable-stayed bridge with ir-regular pylon is taken as the background engineering.Through the detailed finite-element simulation analy-sis,the detailed stress distribution and rigidity of the steel-concrete composite section at the bottom of the ir-regular pylon is studied and analyzed,and the safety factor of the key part at the pylon base is obtained.关键词
