Assessment of Structural Dynamic Response and Vehicle-Track Interaction of Precast Slab Track Systems

Recently, precast slab tracks have been used widely in railway applications, especially in conventional urban railway lines. These types of tracks are rapidly constructed and limit interruptions to train operation. However, the problems of dynamic stability when the trains run on the discontinuous t...
