| Abstract: |
| Based on the theory of nonlocal foundations,the response of beams with nonlocal foundations subjected to moving loads is solved using finite element method.The effects of nonlocal parameter,stiffness,damp and velocity of the moving load on dynamic response are discussed,respec-tively.And the differences between nonlocal and local are compared.The results show that nonlocal parameter,stiffness and damp are the main parameters.The maximum response and the moment it occurs depends on the velocity of moving loads.The results and method can be regard as a reference for track foundation system designed. |
