Determination Of Prestressing Force In Railway Concrete
3} 78 introduction 79 in australia, railway prestressed concrete sleepers have been used in a rail network for nearly 35 80 years in comparison with those experiencing about 50 years in european and japanese rail 81 networks. the railway sleepers (or called ‘railroad tie’ in the us) are a main part of railway track 82 structures. its main duty is to distribute loads from the rail foot to.Abstract pre-stressing in concrete railway sleepers yields endurance property under high-cycle fatigue. this structural effect plays a positive role in durability of the sleepers. however, as a common practice, track engineers often generate holes or web openings in concrete sleepers to enable the accommodation of rail equipment cables and signaling.
