Join us for Part 2 of the fascinating look at the Treetop Trail at the Minnesota Zoo, which converted an existing steel monorail into the world’s longest continuous pedestrian loop. Structural steel was utilized for both strengthening the existing built-up box beam monorail and structuring the new walking path on top of it. Encompassing a 1.25 mile long loop without any expansion joints, balancing thermal and lateral demands also presented a unique challenge for the design team. This session provides a technical deep dive into the structural design challenges and solutions for the project, including an explanation of how the AISC design specifications were applied to this unique structure.
