移动荷载作用下非局部地基梁动力响应分析的有限元法
Dynamic response of beams with nonlocal foundations subjected to moving loads using finite element method
摘要
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 .T he 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 .T he maximum response and the moment it occurs depends on the velocity of moving loads .T he results and method can be regard as a reference for track foundation system desig ned .关键词
