    Abstract
  • In order to improve the computation precision of simplified model for finite element analysis of deck pavement of long-span steel bridge, the size and boundary conditions of the model were optimized by using sub-model technology and comprehensive evaluation method, the parameters sensitivity of the model was analyzed, the reasonable dimension and constraints of a simplified finite element model were put forward, which had 3 longitudinal spans with free borders, 8 U-shape ribs in transverseness with simple supported borders, and 1.2 m-high diaphragms with fixed bottoms.Comparison result shows that simplified finite element model has high precision, the error of transverse tensile strain is only 0.7%, and the error of longitudinal tensile strain is 3.7%.
