Webinar Overview:

Attendees will learn about some of the best practices for steel I-girder bridge design. With over 25 percent of today's bridges involving steel design, this is a market you need to understand. Learn about some of the more critical LRFD design criteria for continuous-span steel I-girder design and how to use Bentley's LEAP Bridge Steel software package to check these important criteria. We'll cover how to better achieve compliance with some of the key AASHTO LRFD design specification limit-state criteria for steel I-girder bridges, and investigate critical sections in an example three-span continuous straight steel I-girder bridge at two different limit states; namely, the design for constructibility in the positive-moment region during the deck-casting sequence and the design of a critical welded stiffener detail at the fatigue limit state. We'll demonstrate how to use LEAP Bridge Steel to check these criteria and some of the steps that can be taken to better optimize the design to satisfy these requirements. Attendees with limited or no experience in steel I-girder bridge design will benefit the most from attending this webinar, but this is also great refresher for more experienced designers. Attendees will be better equipped to utilize LEAP Bridge Steel to produce more cost-effective steel I-girder bridge designs after attending this webinar.
