Simplified Methods for the Analysis and Design of Bridges of Cellular Cross-Section

The paper describes a number of simplified methods that have been developed for the analysis of cellular bridge decks; the behaviour in the linear elastic and in the non-linear post-buckling range is considered. Each method assumes an idealized structural behaviour to provide a simplified solution that may be carried out on a microcomputer. The methods have been developed specifically for use during the preliminary stages of design when repeated analyses may be required to establish optimum proportions. The paper includes some typical comparisons of the results given by the proposed methods with the results of other established methods.
