ANALYSIS OF KANSAS TEST TRACK BEAM RESPONSE

In the fall of 1975 post-mortem static and dynamic tests were conducted on a reinforced twin concrete beam section of the Kansas Test Track (KTT) near El Dorado, Kansas. These tests were part of an extensive program undertaken by the Federal Railroad Administration to gain insight into the mechanisms of the rapid deterioration of that test facility. The data from the static and dynamic tests were used to validate a dynamic track structure model of the KTT beam sections. This report presents a summary of the validation process and the subsequent use of the model as an analytical tool for parameter studies. These studies assist in the investigation of the nature of the KTT beam performance, give insight into the behavior of beam and slab track structures, and provide the technical background for evaluation of future non-conventional track structure designs.
