Webinar: Constructability Of Curved Steel Tub Girders

Seth Greenberg, P.E. from Jacobs, presented the lesson about Constructability of Curved Steel Tub Girders. Tub girders had the complex geometry which was difficult to fabricate. Engineers determined to use tub girders due to its higher torsional rigidity. Seth Greenberg explained the reason for using tub girders, the nuances between different model types, and introduced his favorite features of MIDAS Civil for tub girder construction phases. During the presentation Seth showed how analytical models and their results translated into design objectives with the help of construction stage analysis in MIDAS Civil.
