Steel Bridge Erection Made Simple [B11]

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 without the assistance of software. This session will include an overview of the current UT Bridge software capabilities as well as updated planned for future versions. The focus will primarily be on the analysis of several curved multi-girder, multi-span structures of increasing complexity. Comparison of the results with other commercial programs will be provided.

Complex streel bridge erection can often be tackled with innovative techniques such as a modular construction that can accelerate construction with repeated components prefabricated and rapidly erected. This session will also include a look at experimental results from laboratory testing and numerical analysis related to adjustable steel connections and adjustable steel modules which can form variable depth, efficient structural forms.

Lastly, this session will conclude with the project case study of the unique erection of the John Greenleaf Whittier Memorial Bridge which utilized an overhead gantry assisted twin launched girder system.
