On June 24, 2021, a 12-story condominium building (Champlain Towers South) in Surfside, Florida partially collapsed, resulting one of the deadliest collapses United States history with 98 people confirmed deceased. In this work, we analyze collapse event using video clip that is publicly available from social media. our analysis, apply computer vision algorithms to corroborate new information m...

Casing collapse is one of the major problems in oil fields, imposing a lot of costs on oil companies. This problem occurs not only at drilling times in some formations but also after the completion and production can lead to many problems. Analysis of the behavior of casing collapse in terms of geo-mechanics and solid mechanics could significantly meet the needs of the oil industry of Iran. In ...

In this paper, earthquake-resistance behaviors of existing masonry structures are evaluated based on a certain masonry building. The existing masonry structure is evaluated in its defects of primary design and construction measurements, seismic bearing capacity and durability. Based on results of evaluation, the seismic reinforcement design is introduced for improving earthquake-resistance beha...

Allochthonous masses are common structures in Zagros fold-thrust belt. They are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. However, large allochthonous masses mapped in Dowgonbadan area in Dezful Embayment near the Mountain Front Fault (MFF) of Zagros show characteristics different from the belt common collapse stru...

We prove the existence of energy equilibria of the di-block copolymer problem in the unit disk. They consist of concentrically layered microdomains rich in one of the two monomer building units. We construct them by solving the proper singular limit of the free energy functional. The same limit also explains how under a dynamic law of the free energy, circular interfaces of non-equilibria may m...

JAVMA, Vol 233, No. 1, July 1, 2008 E hazards were an important concern for relief workers following the terrorist attack of September 11, 2001, on the WTC. Building incineration and collapse created a hazardous environment that exposed emergency responders and community residents to a complex mix of toxic chemicals, including Assessment of acute injuries, exposure to environmental toxins, and ...

In line with the current research on the ultimate strength assessment of ship hull girders, careful understanding of the collapse behaviour of unstiffened plate elements within the ship hull girders is an important and necessary task. In this paper, the collapse behaviour of unstiffened plates under longitudinal and transverse thrust is studied by elastoplastic large deflection FEM and the char...

Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. This method is suitable especially in the case of blast-induced progressive ...
