Atlanta Botanical Gardens Walkway Collapse Investigation
On December 19, 2008 a large portion of the S-shaped, steel-framed walkway under construction at the Atlanta Botanical Gardens suddenly foot-long canopy bridge was designed as a cable-stayed structure. At the time of collapse, temporary shoring tower frames and helical piles supported the walkway framing system. This case-study presentation highlights the importance of understanding movement and structural behavior in permanent design, temporary design, and collapse investigation.
