FINITE-ELEMENT PROGRAM FOR ANALYSIS OF FOLDED-PLATE BRIDGE SUPERSTRUCTURES

The behavior of bridge superstructures such as box girders and T-beams is similar to that of a folded-plate structure. A simplified finite-element program, FAP, specifically developed for the elastic analysis of constant depth and straight folded-plate typw structures is presented. Being a specific-purpose program, it can be used by a bridge engineer without the extensive training, knowledge, and effort that may be required for finite-element programs developed for the analysis of a wide range of structural types. Most of the data for FAP analysis is generated by the program from inimal and straightforward input information. FAP has been developed with particular emphasis on practical design and construction considerations. It has already been used for the design of several bridge superstructures. FAP can facilitate the design of many folded-plate type bridge superstructures, especially in those cases in which the design may otherwise be a difficult and time-consuming effort because of the complex geometrical, loading, support, or construction conditions. The illustrative examples presented indicate that the results of analyses using FAP are in good agreement with those based on more exact theories and experimental data.
