Advanced Analysis Techniques for Design and ErectionEvaluating the stability of curved and/or skewed I-girder bridges during construction is of critical importance to designers and erectors; however obtaining a good model of the bridge during these phases can be very difficult. This presentation will look at the analysis of several curved multi-girder; multi-span structures of increasing complexity. Through-plate girders (TPGs) are a common structural choice for medium span railroad bridges and knee brace connections are integral to their behavior. This presentation will summarize results of finite element studies; field instrumentation results and proposed change to AREMA.
