Development of Rotation Capacity Model for Web Cleat Connections against Progressive Collapse: Bayesian Approach

Twenty Years of Advances in Disproportionate Collapse Research and Best Practices since 9/11/2001

“…Steel structures are the focus of four papers (Kong et al 2021;Qian et al 2021;Song 2022;Kong et al 2022). Kong et al (2021) report their experimental and numerical findings on the progressive collapse behavior of scaled six-column subframe composite floor systems subjected to the removal of a side column.…”

“…It is found that the braces can indeed increase the load-resisting progressive collapse capacity and this can be attributed to tensile braces mostly. Song (2022) investigated the required rotation and tension capacities of steel bolted connections to permit the development of catenary action in supported beams to prevent progressive collapse under column loss scenarios using both experimental and analytical methods. Acceptance criteria for steel bolted connections that are based seismic conditions (GSA 2016; US Dept.…”
