Analysis on mechanical performance of integral joint of steel girder bridge with different splicing positions
Taking a 108 m steel truss bridge as the engineering background,the finite element analysis software MIDAS/CIVIL was used to establish the full bridge model and compare with the measured data during construction.ANSYS finite element software was used to establish the upper chord integral node A5 model,and the calculated results of the model were compared with the measured data to verify the accuracy of the model.The stress performance of the integral nodes with splice positions of 3 m,3.98 m and 6 m was studied.The results show that the largest deformation of the integral node system occurs at the splice joint.The closer the splice position is to the integral node,the smaller the force and deformation of the splice plate.The results can provide guidance for engineering design and practice.
