Analysis on the force of pushing construction of steel girder with undercarriage
In this paper,based on the steel girder project of the new overpass in Longyou Station,the structural response of the overpass is simulated and analyzed by numerical simulation method.The results are as follows:in different construction stages,the stress distribution of the steel girder shows significant dynamic changes,especially in the cantilever area and the straight belly bar area;The maximum deflection of steel girder mainly occurs at the beam of roof.There is a positive correlation between the reaction force and the distance of the cantilever during the pushing process.The design scheme meets the specification requirements of anti-overturning and local stability.The research results can be used for reference in similar projects.
