Title: Application of Substructure in the Fatigue Analysis of Steel Truss Bridge
Abstract: A FEM model of steel truss bridge was built based on the method of substructure.As welded joint was easy to suffer fatigue failure,a model of joint was built as a substructure by the way of super element.Under the actions of live loads,the stress and deformation was analyzed.The results are accurate,and show the fatigue damage of joint;moreover,it save computing time under limited computing resource.So,we can draw an conclusion that this method is efficient and of highly practical in the fatigue analysis of truss bridge.
