Analysis of dynamic and static characteristics of pipeline suspension bridge with wind cables

Anotace: In this paper, a suspension bridge carrying oil pipelines is taken as the research object. A spatial finite element analysis model of the bridge is established for the bridge by using MIDAS/CIVIL finite element analysis software, and the structural analysis of static and dynamic characteristics is carried out. The analysis of dynamic characteristics shows that the wind cable can greatly improve the natural vibration characteristics of the suspension bridge. The analysis of static characteristics shows that the internal forces of the suspender are evenly distributed and the vertical displacement of the main girder of the steel truss is distributed in a parabola, besides, the strength of each main component can meet the safety needs.
