| Abstract: | In the light of the characteristics of the Bailey truss,this paper sets up a finite element model for the truss that considers the secondary internal force. By way of example of a practical Bailey truss form traveler used for construction of a bridge,the paper respectively makes the simplified calculation,finite element numerical simulation and also the comparative analysis of the calculation and simulation. The results of the analysis show that the influences of the secondary internal forces of the vertica... |
