Abstract: Since the thickness of the deck of the assembled steel truss-concrete composite continuously ridged bridge is fairly thin, adopting finite element analysis software can not directly calculate the deck’s lateral stress states. For decks with fairly large width-span ratio,using Structural Mechanics Solver and the finite element software MIDAS is a simplified method to analyse the deck’s lateral stress distribution and get the distribution law of lateral stress, which is expected to have a guidance significance to engineering.
