2경간 연속 이중합성 소수주형 철도교량의 동적해석

초록

This paper deals with the influence of train on the dynamic response of steel composite railway bridges. The bridge system which has two I-girder and several cross beams is modeled with plate and frame elements, with lower slab by the internal hinge for properties of concrete and upper slab is assumed to be fully connected with girders using rigid links. Model is performed with the moving train load and considered bouncing and pitching motion of the deck of bridge To investigate the behavior of bridges due to moving trains, parametric studies on the speed of train to the double composite bridge are performed.
