Introducing a New Limit States Design Concept to Railway Concrete Sleepers: An Australian Experience
Over 50 years, a large number of research and development projects with respect to the use of cementitious and concrete materials for manufacturing railway sleepers have been significantly progressed in Australia, Europe, and Japan (Wang, 1996; Murray and Cai, 1998; Wakui and Okuda, 1999; Esveld, 2001; Freudenstein and Haban, 2006; Remennikov and Kaewunruen, 2008). Traditional sleeper materials...
متن کاملAutomating condition monitoring of wooden railway sleepers
68 October 2007 EngineerIT This article aims to automate such intuitive human skills for future sleeper inspections. Pattern recognition has been proposed for classification and results from sensors based on the abovementioned methods were fused to generate a single output condition. Final results achieved in this work indicate an overall classification rate of around 88% compared to the human ...
متن کاملEmbedding Wireless Sensors in Railway Sleepers
In recent years there has been intensive research and development in the application of wireless sensor network (WSN) technologies to various sectors such as healthcare, home automation, environmental monitoring and the monitoring of large structures, eg, buildings and bridges. The monitoring of railway infrastructure such as the tracks, bearers and sleepers is another area that could potential...
متن کاملinvestigation on the accuracy of the current practices in analysis of railway track concrete sleepers
in this paper, the main factors in the analysis of the railway concrete sleepers areinvestigated and new recommendations are made in order to improve the accuracy of the currentpractices in analysis of the railway track system. first, a comprehensive literature survey isconducted, then, fem models for a railway track system are developed and used to discuss andevaluate the assumptions commonly ...
متن کاملInvestigation on simulation of train loading on prestressed concrete sleepers
Railway concrete sleepers have been developed and utilized in railway industry for over 50 years. Cyclic loading because of vibration on sleepers due to the train loading and the velocity of train itself and also a small percentage of bad wheels, can eventually lead to a crack network and failure of component. The objective of this study is to investigate the load carrying capacity of the selec...
