Analysis of Influence on Mechanical Behavior of Jiubao Bridge Caused by Construction Process

Abstract:

Construction procedure of the tie arch bridge with steel-concrete composite girders affects the mechanical behavior of the whole bridge significantly. Space finite element model of Jiubao Bridge was established. Different construction procedures of the tie bars and bridge decks were proposed and the stress of upper and lower flange of the girder and the concrete bridge decks under construction schemes had been analyzed. The calculation results show that the scheme that the tie bars are stretched finally can reduce the tension stress of the bridge decks significantly. The construction scheme that the bridge decks are constructed on full space supports is favorable to the girder over the V-shaped piers.
