Research on Longitudinal Creep Mechanism of Curved Girder Bridges Based on Abaqus Analysis
Curved girder bridges are widely employed in highway construction,yet their notable coupling effects of bending and torsion,along with uneven distribution of bearing reactions,often lead to displacement and creep of the girder.This paper,anchored in a case study from a high-speed interchange project in Zhejiang Province,em-ployed the finite element analysis software Abaqus to establish a refined model,taking into account the nonlinear friction behavior between bearings and upper and lower bearing pads.By applying linear temperature cycling loads,it elucidated the longitudinal creep characteristics of the superstructure of curved girder bridges after five cycles of overall heating and cooling.The findings serve as guidance and reference for the selection of rational support sys-tems during the design phase of curved girder bridges and the prevention and control of creep disorders during oper-ation.
