The Determination of the Track Modulus k for the Standard Track Analysis


After the adoption of the equation EIw^(iv) + kw = q for cross-tie track analyses, a number of methods for the determination of the track modulus k were proposed and used during the past several decades. However, some of these methods are difficult to utilize or are of questionable validity. Therefore, at first, a simple yet accurate method is presented and its use is illustrated on practical examples. Then, other published methods are critically reviewed and their shortcomings are pointed out.
