Impact of Tension Sequence of the Tensile Rod of Steel-Concrete Transition Section on Local Mechanical State of Bridge Arch Ribs
In order to clarify the impact of the tension sequence on the local mechanical state of the bridge arch ribs,and then obtain the optimal tension sequence,the steel-concrete transition section of the arch rib of the swallow type steel box arch bridge was taken as an example.The finite element model was established by ABAQUS software to study the impacts of long and short rods,long and short sides and inner and outer ring tension sequence on the axial force of the tie rod,the concrete preloading effect and the equivalent stress state of the pressure plate in the steel-concrete transition section.The results show that the tension sequence of the short rod before the long rod,the long side before the short side,the inner ring before the outer ring can improve the uniformity of the axial force of the tie rod and the preloading effect.The relevant conclusions can provide reference for the study of tension sequence of similar rods.
