Comparison betwixt existent and simulated illness process. Credit: Andy Slater
On June 24, 2021, astatine astir 1:30 a.m. Eastern Daylight Time, Champlain Towers South Condominium, a 12-story 40-year-old reinforced factual level sheet operation gathering successful the Miami suburb of Surfside, Florida, United States, experienced a abrupt partial collapse. Ninety-eight radical were confirmed dormant and eleven others were injured. What has caused the abrupt illness of this level sheet building?
Professor Xinzheng Lu from the Department of Civil Engineering, Tsinghua University is moving toward analyzing the imaginable causes of the building's illness and reconstructing the illness process for a amended understanding.
In this study, Professor Lu and his probe squad analyzed the wide show and the cardinal components of the collapsed gathering based connected the gathering plan codes. In addition, punching shear and post-punching performances of a emblematic slab-column associated were studied done the refined finite constituent analysis. Furthermore, the illness process was besides simulated and visualized utilizing a physics engine.
Through these analyses, respective conclusions were reached, including (1) the punching shear strengths of the cardinal joints and the axial compressive strengths of the columns of the collapsed operation are debased and incapable to conscionable the requirements of the existent plan codes; (2) emblematic slab-column joints person constricted spot astatine the ample deformation signifier owed to mediocre reinforcement detailing.
In summary, the collapsed operation has a debased level of information margin, robustness, and absorption to progressive collapse, which tin inevitably pb to superior consequences if section harm occurs owed to unexpected and unforeseeable reasons.
