“…This contributed to a more precise approximation of blast loads allowing more complicated real scenarios to be modeled and more optimized design to be achieved. Using ALE method, Zhao et al (2012) investigated the response of reinforced concrete containment of an nuclear power plant under internal blast loading, Neuberger et al (2007a, b) applied it to study armor plate response under air blast and buried charges detonation. Zakrisson et al (2012), Zakrisson et al (2011) investigated the plate response under blast loading modeling cylindrical explosive geometry in a steel pot according to NATOs standard AEP-55) requirement.…”

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.

“…In terms of dynamic performance, the high density of the concrete provides inertia force improving blast resistance compared to a single steel plate. The panels could be used in military shelters and nuclear power plants station or barriers for protection of the building and critical infrastructures [1][2][3]. Wang et al [4] studied the performance of curved SCS panel used for offshore structures and identified different failure modes.…”

The safety of the civil structures could be significantly improved against shock waves and blast loads by using steel concrete steel (SCS) protective walls. A numerical study has been performed to simulate the response of SCS wall subjected to a near-field blast load. A conventional SCS panel subjected to near-field blast load and its structural performance is evaluated in terms of maximum damage and deformation. The simulations performed using ABAQUS\EXPLICIT finite element package and built-in concrete damage plasticity concrete constitutive formulation. The maximum deformation, plastic strain, and failure mode under different loading scenarios have been investigated. The aim of this study is predicting the structural response of the SCS panel with different blast charge and identification of optimum configuration in terms of concrete strength and plate thickness. In the second part of the study, two novel sandwich configurations consisting of a corrugated metal sheet and the concrete core are proposed and compared with the conventional protective walls. The optimum parameters for each structural component are identified using an optimization procedure. Based on this study, using the proposed wall configuration will results in superior performance compared to the conventional walls while the extra cost of fabrication is insignificant.

“…An explosive detonation was conducted on air blast, blast in confined space [15] and, consequently, direct contact with blast load [9,16]. Blast in confined space will trigger more energy concentration while the pressure behavior in air blast is low frequency blast vibration.…”

“…It is because air overpressure waves radiate outward to the air surrounding then lower the energy waves concentration [17]. The extreme energy from detonation can create impulsive impact and in consequence, many researchers proposed the high strength of the concrete structures [12][13][14][15]26]. Therefore, this paper reviews on the geopolymer concrete performance towards explosive blast loading.…”

Abstract. The severe damage to civilian buildings, public area, jet aircraft impact and defense target under explosive blast loading can cause a huge property loss. Most of researcher discusses the topics on design the concrete material model to sustain againts the explosive detonation. The implementation of modern reinforcement steels and fibres in ordinary Portland cement (OPC) concrete matrix can reduce the extreme loading effects. However, most researchers have proved that geopolymer concrete (GPC) has better mechanical properties towards high performance concrete, compared to OPC. GPC has the high early compressive strength and high ability to resist the thermal energy from explosive detonation. In addition, OPC production is less environmental friendly than geopolymer cement. Geopolymer used can lead to environmental protection besides being improved in mechanical properties. Thus, this paper highlighted on an experimental, numerical and the analytical studies cause of the explosive detonation impact to concrete structures.
