Abstract:Aimed at analyzing the influence degree of initial geometry defect on the ultimate bearing capacity CFST arch bridge, the paper introduces the study of influence of initial geometry defect on the ultimate bearing capacity of Concrete-Filled Steel Tubular arch bridge through applying different scale and different form initial geometry defects by finite elements method. The simula- tion results show that initial geometry defects can exert an evident influence on the ultimate bearing capacity of CFST arch bridge. The paper suggests a greater attention to the application of initial geometry defects in practical engineering.
Keywords:Concrete-Filled Steel Tubular(CFST) arch bridge  initial geometry defect  ultimate bearing capacity  simulation
