“…Soutis et al (2011) studied the response of GLARE panels to air blast loading using both, ALE and ConWep methods. In other studies ALE method was also used in variety of different applications and purposes: Chafi et al (2009), Chung Kim Yuen et al (2012, Fox et al (2011), Jayasinghe et al (2013, Langdon et al (2010), Liu et al (2012), Ma et al (2013), Pi et al (2012), Spranghers et al (2013), Tai et al (2011). In order to efficiently represent FSI on higher scaled distances, other techniques like coupling of the empirical ConWep model with ALE (Todd (2010)) or ALE mapping techniques are used (Luccioni et al (2006), Zakrisson et al (2011)).…”

The Multi Material Arbitrary Lagrange Euler (MMALE) method is widely used method for numerical investigation of structural response under blast loading. However the method is very demanding for use at the other hand. In this paper are presented the results of the detailed numerical investigation in order to simplify some decisions contributing to the accuracy and efficiency of this model. The influence of mesh properties (particularly mesh size, its biasing and distance of the boundary (DoB) conditions from the deforming structure) on blast wave loading parameters and structural response is investigated in detail and based on the results minimum mesh design criteria is proposed. The results obtained are presented as a function of the scaled distance and additionally related to the radius of the charge. Validation studies were also done successfully.

 Pile foundations are commonly used as foundation systems for high-rise buildings and bridges. This paper uses a fully coupled three dimensional numerical modelling procedure to study the performance of pile foundations subjected to ground shocks induced by surface explosions. The comprehensive numerical model includes the pile, surrounding soil, air and the explosive. Appropriate material models are incorporated and dynamic non-linear analysis is carried out using finite element techniques. The soil in which the pile is buried could influence the blast performance of the pile. A parametric study is hence carried out to evaluate the effects of soil properties of density, friction angle, cohesion and Poisson's ratio on the blast performance of the pile. It is found that density and cohesion of soil have significant effects on the deflection of the pile under blast loading. Poisson's ratio has some effect, but effect of the soil friction angle is not very significant. The findings of this study will serve as a benchmark reference for future analysis and design of pile foundations to blast loading.

Article HistoryReinforced concrete (RC) column systems are widely used in protective structures designed to resist blast events. Development of correlations between explosive load and the resulting damage in concrete elements are significant for incorporation of blast load in design and also for pre and post-damage assessments. The main purpose of this research is to organizing correlations between explosive load and damage. These correlations are being expressed in Pressure-Impulse diagrams. The damage level is calculated based on the residual axial load-carrying capacity of the damaged RC column. Finite element modeling in LS-DYNA is used to analyze the structures and calculate the damage level for each explosive phenomenon. The Arbitrary Lagrangian Eulerian (ALE) method is used to simulate the explosive loads in the reinforced concrete column. The results demonstrated that increase the column size cause to increase in pressure and impulsive asymptotes and lead to enhanced the pressureimpulse (P-I) diagram.Contribution/ Originality: Current knowledge on quantifying and predicting explosion damage of RC columns subjected to blast effects is incomplete and limited. This research examines the damage analysis of RC columns using P-I diagram. The P-I diagrams are developed to determine levels of damage on a structure and have also been used in the past to evaluate human response to shock wave generated by an explosion.
