A preliminary analysis and discussion of the condominium building collapse in surfside, Florida, US, June 24, 2021

Abstract On June 24, 2021, a 40-year-old reinforced concrete flat plate structure building in Miami suffered sudden partial collapse. This study analyzed the overall performance and key components of collapsed based on design codes (ACI-318 GB 50010). Punching shear post-punching performances typical slab-column joints are also studied through refined finite element analysis. The collapse process was simulated visualized using physics engine. By way these analyses, weak points highlighted. differences between reinforcement detailing requirements current Chinese code discussed, together with comparison punching performances. procedure debris distribution compared actual scenes.
