Abstract
This paper presents a comprehensive outline of a practical computer-based bridge analysis process which allows incorporation of nonprismatic member behavior. Unique to this analysis process is the development of mathematical relationships which are used to calculate internal member forces, eliminating the need to formulate and save in memory each and every influence line for the structure under consideration. Application of this bridge analysis procedure is shown to be remarkably reliable and accurate in comparisons with theoretically exact analysis results. In addition, the analysis procedure presented is economical in terms of computational time and computer memory requirements.
