Finite Element Analysis of Prestressed Concrete Sleeper Subject to Static Loading
About this article
Abstract
Railway is one of the most important, reliable, and widely used means of transportation, carrying freights, and passengers. Thus, a study on railway is indeed important for the development of railway engineering and technologies. Prestressed concrete sleepers are the main structural elements of railway tracks. They play a vital role in railway track performance, behaviour, and safety. The main objective of the study is to develop a three-dimensional finite element model of prestressed concrete sleeper to compare load-deflection of finite element analysis and experimental result and identify the behaviour of the sleeper subject to static loading. The three-dimensional element analysis is executed using LUSAS. A concrete element is modelled as a hexahedral element and prestressing tendon is modelled as a bar element. Later, a positive moment test is carried out on the model and at last, a validation of the finite element model through comparison with the experimental load-deflection response is presented in this study. Thus, good agreements between finite element analysis and experimental results make the work beneficial and reliable.
