| Abstract: | The action between bridge and ballasted jointless turnout on bridge is reversible. To locate the force path between them, the model of a jointless turnout on a 4×32 m continuous beam were calculated and analyzed. Also analyzed were factors of influence, such as: temperature increment, longitudinal pier stiffness, ballast resistances, and turnout and bridge layouts. |
