“…For structures built from primarily brittle materials, such as concrete and masonry, the higher levels of damage result in particulate breakage and fragmentation, especially in the dynamic loading region of the pressureimpulse diagram. Various trials have observed high levels of initial fragmentation when subject to blast loads [12], with near-field detonations producing the highest level of fragmentation and spalling [13,14]. Many research studies have investigated different aspects of blast induced fragmentation of brittle materials, such as the debris launch velocity [15,16], fragment size [17], ground impact reaction [18] and general statistical descriptions [19].…”

“…In the past studies, most of the experimental set up on concrete blasting was conducted through air blast conditions [8,18,19]. The critical considered parameter in experimental before setting up the blast events are standoff distance, mass of explosive, types of explosive and concrete model material.…”

A 2D finite element model was simulated by using LS-DYNA for modelling fiber reinforcement concrete and predict the observed damage [8]. Next, the numerical simulation of the dynamic response and residual axial capacity of composite columns was also investigated by using LS-DYNA [9].…”

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.

SummaryIn this study, the damage to a reinforced concrete column retrofitted by steel jacket subjected to blast loading was investigated. Actually, this research is an extensive study of the previous works of the authors. Therefore, some of finite element modeling and validation procedure were adopted. Extensively, the effect of the steel jacket used for retrofitting the reinforced concrete column was evaluated. The effects of scaled distance, axial compressive force, and steel cover plate thickness on the structural performance of the column were investigated and discussed. Moreover, the residual strengths of the column with respect to the different scaled distances were also evaluated. Some useful discussions and recommendations, which may interest structural engineers and researchers, were presented as an important outcome of this research.
