Few absolute guidelines are available for the selection of an analysis method. The number of permutations resulting from various combinations of complicating physical features and mathematical models is virtually boundless. This decision should be based on an evaluation of the nature and complexity of the structure, a thorough understanding of the expected behavior, and knowledge of the capabilities and limitations of the various analysis options. Therefore, this module provides an overview for the structural analysis of steel girder bridges. Discussions include the applicable loads, descriptions of the various tools and techniques available, and considerations for selecting the appropriate application or technique for a given bridge.96
