Book excerpt: Excerpt from Bulletins and Convention Proceedings of the American Railway Engineering Association (Engineering Division, Association of American Railroads), 1961-1962, Vol. 63 It has often been suggested that the present design specifications for the distribution of live load in railway bridge floors, although giving satisfactory designs, are generally too conservative. With this in mind, the study summarized herein was undertaken at the University of Illinois to develop a more realistic specification for the distribution of live load in the floor systems of steel railway bridges. The first portion of the study consisted of the preparation of a review of the existing methods of analysis for bridge floor systems and related structures, and then the devel opment of methods of analyses to accurately determine the distribution of wheel loads to bridge floor systems. The second objective of the investigation was to obtain a num ber of solutions of simulated bridge floors using these methods of analysis. These solu tions include evaluations of the two general types of bridges now in use and are com pared with the results of a number of actual bridge tests conducted during the last 10 years by the Association of American Railroads The third and final objective was to derive for design office use, a method of computing the live-load distribution which takes into account the principal factors affecting the distribution.
