“…Wang et al (2012) studied the underwater blast performance of foam cores and CFRP sheets which were graded density. Pantelides et al (2014) discovered the performance of FRC wall panel which has a square shape of size 1.2m under blast. Dear et al (2017) tested the air and underwater blast of various polymeric foam and face sheet composite sandwich panels by TNT proportionate charge of 100 kg at 15m stand-off.…”

According to National Crime Record Bureau (NCRB) report, accidents due to Fire has been ranked fifth it’s up by three positions from the last year’s ranking and accidents due to fire killed more human lives and lead to property loss. Due to explosive accidents, it revealed that loads, for example, the effect of essential sections, and effect of optional parts, and pressure by reflective and blast waves are generated and it collapses the whole structure. To overcome the damages due to fire accidents, strengthening of members, protection to the structure, design the structural member as a more adequate to resist the blast load and design the structure as a blast resistant may be good. In this paper, various structural members due to blast load and the numerical methods to persist the blast load behaviour are reviewed. The behaviours of various type of concrete under blast load were discussed. Based on the review, it may be concluded that to avoid explosive collapse the structural member has to be designed to withstand the blast waves and utilization of adaptable type materials which was light in weight result by decreasing transfer of energy and less strength, less ductile fibres mixed into the concrete will give blast performance to the concrete.

“…Terrorist attacks on structures may not be eliminated completely, but the effects of these attacks can be mitigated. Several techniques have been developed in recent Fracture Mechanics Applications years for this purpose, such as retrofitting or coating applications [1,2], internal reinforcement [3,4] or geometrical modifications in buildings [5]. It is desirable that mitigation techniques may be applied in both new and existing buildings.…”

Blast loads can represent a great hazard to existing structures. Their effects on structural elements can be decisive for the integrity of both the structure itself and the people within it. The behaviour of the individual elements of a building is totally different due to the heterogeneity of the materials composing them. This fact makes it necessary to carry out tests on each type of structural element in order to correctly evaluate the response of the structure. In addition, the scale effect can produce inaccurate results, making it necessary for tests to be performed on a full scale to validate the results. In this work, the results of several tests with explosives are presented, in different constructive elements, all of them carried out at full scale. These elements range from the structural elements (beams and concrete slabs) to the weak elements of a building (masonry panels).

“…In recent years, experimental investigations have been conducted with the objective of improving the blast-resistant performance of concrete slabs, without increasing the concrete strength or the number of reinforcement bars (Morishita et al 2004), and several researchers have reported the good performance of fiber-reinforced cementitious composites (FRCC) (Banthia et al 2004;Lan et al 2005;Coughlin et al 2010;Foglar and Kovar 2013;Ellis et al 2014;Pantelides et al 2014;Castedo et al 2015;Li et al 2016;Luccioni et al 2017).…”

When designing blast-resistant concrete members that are subject to contact detonation, it is necessary to reduce the spall damage due to tensile stress waves reflected from the back sides of the members. In a previous study, the authors confirmed the good spall-reducing performance under contact detonation of slurry-infiltrated fiber concrete (SIFCON), which is manufactured by first placing fibers into an empty mold and then infiltrating them with grout. In this study, to obtain SIFCON with further improved spall reduction, experimental investigations were conducted regarding the effects of different fiber types on the blast resistance of SIFCON slabs against contact detonation. Five types of steel fibers and four types of synthetic fibers were employed as reinforcing fibers. The thickness of the SIFCON slabs was fixed at 80 mm, and contact detonation tests were conducted using two amounts of SEP explosives. All of the SIFCON samples investigated reduced the spall damage due to contact detonation more effectively than normal concrete and other conventional fiber reinforced cementitious composites. Furthermore, by using SIFCON with fine straight steel fibers, the spall-limit thickness of the slab could be reduced by 54% or more.
