A forensic analysis of the Florida International University pedestrian bridge collapse using incident video footages
Highlights This study analyzed the FIU bridge collapse using public scene videos and photos. The use of FEA sued the photogrammetric evidence to simulate the collapse event. The diagonal web #11 bore the most stress during construction before the collapse. The diagonal web #11 failure led to the progressive collapse of the bridge.
Abstract On March 15, 2018, a Florida International University (FIU) pedestrian bridge near Miami, Florida collapsed during construction. The abrupt failure resulted in casualties and garnered worldwide attention. In the present study, a preliminary forensic analysis of this incident was carried out using limited evidence collected from the collapse scene videos recorded by bystanders. This study is limited in its scope in that it is confined to the examination of how the sequence of failures unfolded by interpreting the rough measurements extracted from the videos through the prism of a physics-based (finite element) model of the bridge. The study does not attempt to explore why this incident may have happened. Nevertheless, by identifying how the collapse occurred, it may be possible to better understand the root causes of this unfortunate incident by combining this information with other, more detailed forensic data. Incidentally, this study provides a new avenue for structure collapse analysis by exploiting incident scene videos and wreckage photos obtained from the public domain.
