Advanced Analysis Techniques for Design and Erection [B3]

Evaluating 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.
