“…For decades, previous studies have utilized fiber-reinforced composites at both material and structural levels to improve the blast and impact resistance of cement-based composite materials (Yamaguchi et al 2011;Silva and Lu 2007;Ohkubo et al 2008;Ha et al 2011;Wu et al 2009;Mosalam and Mosallam 2001;Razaqpur et al 2007;Xie et al 2014;Ohtsu et al 2007;Lan et al 2005;Soe et al 2013;Nam et al 2010;Kim et al 2015;Li et al 2016;Coughlin et al 2010;Yoo et al 2015;Kim et al 2015;Yoo and Yoon 2016;Nam et al 2016). Yamaguchi et al (2011) reported that polyethylene fiber-reinforced concrete has superior blast resistance under contact explosions as compared with normal RC.…”

This study investigates the blast resistance of fiber-reinforced cementitious composite (FRCC) panels, with fiber volume fractions of 2%, subjected to contact explosions using an emulsion explosive. A number of FRCC panels with five different fiber mixtures (i.e., micro polyvinyl alcohol fiber, micro polyethylene fiber, macro hooked-end steel fiber, micro polyvinyl alcohol fiber with macro hooked-end steel fiber, and micro polyethylene fiber with macro hooked-end steel fiber) were fabricated and tested. In addition, the blast resistance of plain panels (i.e., non-fiber-reinforced high strength concrete, and non-fiberreinforced cementitious composites) were examined for comparison with those of the FRCC panels. The resistance of the panels to spall failure improved with the addition of micro synthetic fibers and/or macro hooked-end steel fibers as compared to those of the plain panels. The fracture energy of the FRCC panels was significantly higher than that of the plain panels, which reduced the local damage experienced by the FRCCs. The cracks on the back side of the micro synthetic fiber-reinforced panel due to contact explosions were greatly controlled compared to the macro hooked-end steel fiber-reinforced panel. However, the blast resistance of the macro hooked-end steel fiber-reinforced panel was improved by hybrid with micro synthetic fibers.

“…e largest portion of conducted field tests is related to the research of behaviour of concrete slabs [4,9,[11][12][13][14]. Researchers are focused on detecting new ways for slab strengthening by using different types of materials as concrete aggregate [15], adding steel [16][17][18][19][20][21], carbon [22], and polypropylene [4,23] fibres or using higher resistance concrete classes [24]. Experiments on columns are also conducted in the attempt to determine whether or not seismically designed bridge or building columns are capable of sustaining significant blast load before collapsing or is it necessary to conduct retrofitting [5,[25][26][27][28][29][30][31].…”

A brief review of experimental methods for testing blast effects on structures is presented. Methods are classified in four groups: field tests, shock tubes, pendulum systems, and new techniques (blast simulator). Description of each method is given together with overall specification of possible instruments used in each test. In today’s modern era of computers which are becoming powerful tool implemented in all aspects of life and also scientific research, comparison of experimental and numerical techniques is also given. Comparison of data obtained from different experimental methods show that careful planning and execution leads to reliable results in terms of pressure, impulse, stress, and damage quantification.

“…In this respect, an attempt to incorporate the superior impact-resistance of FRC into protective and blast-resistant concrete structures can be regarded as one of the emerging issues. Although some researchers have also investigated the structural behavior of FRC structures under highspeed impact loading based on computer analysis (Coughlin et al, 2010;Ohtsu et al, 2007;Teng et al, 2008), the safety-related http://dx.doi.org/10.1016/j.nucengdes.2016.04.038 0029-5493/Ó 2016 Elsevier B.V.
