Abstract

During the traditional incremental launching method for steel box girder, high-performance launching equipment, more accuracy and stronger temporary piers are needed because of the exaggerated gravity caused by upper plate, which leads to the cost increasing. It can even cause damages at the support points due to the enormous gravity for the thin wall steel box girder. In order to prevent above failure, an improved incremental launching method is proposed for steel box girder. Five pushing cases, stresses distribution, buckling at the mid-span and so on are analyzed by software ABAQUS. The result shows that this improvement method can meet the requirement of incremental launching construction; the deformation and stress in the pushing process meet the requirement.
