| Abstract: | A finite element mechanics model to calculate the temperature force and displacement of the joiless switch on simple supported beam bridge by using the finite element method. The forces and displacement ofjoiless switch are computed, and the influences on seamless turnout of bridge structure are analyzed. The results could be used to guide the design of joiless switch on bridge. |
