“…The column deflections subjected to the blast load were similar for the buildings with different aspect ratios. Nica et al 34 performed a numerical analysis to perceive the collapse of RC framed buildings subjected to the blast loads. The analyses were performed utilizing the applied element method.…”

“…It is obtained key parameters to define the performance of structures under blast loading. Nica et al 34 performed a numerical analysis of collapse due to blast action for a RC building. In the study, the demolition scenario is introduced to demonstrate the utility of the applied element method to observe the load redistribution mechanism in the case of failure of several columns.…”

Accidental loadings such as blast loadings constitute the great majority of potential and actual fatalities in industrial facilities. To prevent human loss and injuries, and for a safe design or blast assessment of an industrial building, the risks of these accidental loadings should be quantified in terms of both probability/frequency and consequence aspects. In this paper, we propose a combined risk‐based approach for the assessment of all accidental loadings. The study includes a newly developed risk‐based method that can be used for blast analyses of buildings in industrial facilities. The methodology is introduced for blast design/analysis of structures in industrial facilities with explosion hazards. Within this scope, the paper presents an evaluation of explosion hazards in industrial facilities. The study also focuses on a series of vital phases in the analysis and design stages, including explosion modeling, building screening analysis, detailed structural analysis, conceptual structural upgrade design, and final upgrade design. Finally, upgrade techniques for buildings in industrial facilities against explosions are also provided to minimize the individual risk.

The damages and casualties inflicted by mine and IED attacks in security challenging areas generated a strong and quick response from nations all over the world. As a part of this response several national and private research facilities increased their efforts in identifying and implementing new ways or technologies to enable blast wave mitigation. The current paper aim to investigate the opportunity of using polyurea coated steel plates as a possible new blast mitigation approach, as suggested by several investigators. In order to objectively conclude about the ability of polyurea coated plates to sustain locally blast loads several experimental tests were performed according to STANAG 4569 demands for a 1/6 scaled plate structure. In order to numerically validate the experimental results several Autodyn simulations were set-up. The numerical and experimental results exibits a fair correlation, both pointing towards a dismiss of the idea of using polyurea coated steel plates as structural and cost effective blast mitigation approach.
