Modeling buildings response to blast and subsequent progressive collapse interested more and more researchers during the past two decades. Due to the threat from extreme loading, efforts have been made to develop methods of structural analysis and design. In this paper, progressive collapse capacity of steel moment frames was first investigated using alternate load path method, then a nonlinear...

Extensive research has been focused on the progressive collapse analysis of buildings and most of them are based on the alternative path method (APM) with sudden removal of one or several columns. However, in this method the damage of adjacent elements of removed columns under blast conditions was ignored and this issue can lead to an incorrect prediction of progressive collapse. Therefore, in ...

purpose: since explosive blasts continue to cause casualties in both civil and military environments, there is a need for an understanding of the mechanisms of blast trauma at the human organ level, plus a more detailed predictive methodology. the primary goal of this research was to develop a finite element model capable of predicting primary blast injury to the lung so as to assist in the dev...

Ocular injuries from blast have increased in recent wars, but the injury mechanism associated with the primary blast wave is unknown. We employ a three-dimensional fluid-structure interaction computational model to understand the stresses and deformations incurred by the globe due to blast overpressure. Our numerical results demonstrate that the blast wave reflections off the facial features ar...

Building facades in commercial and residential buildings in Australia, UK and elsewhere are highly vulnerable to terrorist threats involving explosive blast loading. The modelling of consequences to built infrastructure when subject to blast loading is well developed; however, considerable uncertainty remains with respect to system response and explosive loading parameters. In this paper, struc...

The modelling of consequences to built infrastructure when subject to blast loading is well developed; however, there is considerable uncertainty and variability with explosive loading and system response; which provides many challenges for collateral damage estimation. In this paper, structural facades are assessed – with a focus on glazing – as this is a structural and load-capacity system th...

An experimental investigation was conducted to evaluate the dynamic performance of E-glass Vinyl Ester composite face sheet / foam core sandwich panels when subjected to pre-compression and subsequent blast loading. The sandwich panels were subjected to 0 kN, 15 kN and 25 kN of in plane compression respectively, prior to transverse blast wave loading with peak incident pressure of 1 MPa and vel...

Obstructing the passage of blast waves is an effective method mitigating pressures downstream obstacle. To this end, interaction between a wave and simplified structural shape, such as cylinder, has been widely investigated to understand complex flow pattern that ensues around The patterns include interference zones incident wave, diffracted other secondary in region. Such are responsible for c...

Need for designing certain important structures to resist blast loads is increasing in the recent past years, due to the enhanced terrorist operations. A bomb explosion can cause very serious damage on the building's external and internal structural frames. Collapse of one structural member in the vicinity of the source of explosion, may then create critical stress redistributions and lead to c...
