(PDF) Review paper on blast loading and blast resistant. Abstract the research reviews the various methods, accurate and approximate, analytical and numerical, used for the analysis of beams that are subjected to dynamic loads., design with regard to blast- and fragment loading freedom analysis and simplified hand calculation in order to verify the fe-results. concerning the impact of the fragmental loads appearance, it turned out that simplified and more advanced analyses, generates similar results. however, when the loss of stiffness and mass, due to fragmental penetration of the beam, are taken into account.

Response of an energy-dissipating system to simulated blast matthew gow master of applied science in civil engineering graduate department of civil and mineral engineering university of toronto 2015 abstract explosions generate extreme overpressures that can cause irreparable damage to critical infrastructure. to mitigate this damage, an energy-dissipating system has been developed that limits, the behaviour of cross-laminated timber elements subjected to simulated blast loads by dominic cote thesis submitted in partial fulfillment of the requirements for the degree of master of applied science in civil engineering under the auspices of the ottawa-carleton institute for civil engineering university of ottawa october 2017 dominic cote, ottawa, canada, ….

The focus of this research was the analysis of polymer sheets as a method for retrofit design. many materials have been tested for blast retrofit design but have shown and a commonly used sdof analysis tool, sbeds are employed for the purpose of analysis. iv a parametric analysis is conducted to develop pressure-impulse (pi) curves for different damage levels. curve fit analysis was performed to characterize the pi curves generated from fe method. conclusions and future work recommendations are presented for design of reinforced concrete slabs for blast

Non-linear analysis of sdof system under blast load by assal t. hussein, 2010 this paper presents the analytical methods of sdof system analysis subjected to blast loadings. two types of blast wave were applied for studying the nonlinear behaviour of a system, the analysis focused on the displacement time history responses which develop the basis for studying the behaviour of sdof system under initially, the blast wave increases to a pressure value above the ambient atmospheric pressure, known as the peak overpressure. this overpressure decays as …

This paper includes an investigation for the deformations, including deflections and damage modes, which occur in reinforced concrete (rc) slabs when subjected to blast loads of explosions. the slab considered was subjected to close-in detonations of blast design is a necessary part of design for more buildings in the united states. blast design is no longer limited to underground shelters and sensitive military sites, buildings used by the general public daily must also have satisfactory blast protection.
