“…e BakerRisk test site in San Antonio [42] has a 0.75 m 2 (8 ft 2 ) target area in its normal configuration and can be configured to deliver a variety of blast pressure and impulse combinations with maximum possible peak pressure of 3 bar (45 psi) with a maximum impulse greater than 660 bar·ms (1000 psi ms). Shock tubes of similar construction and capability are blast load simulator (BLS) which are situated at the U.S. Army Corp of Engineers (USACE) Engineer Research and Development Centre (ERDC) in Vicksburg, Massachusetts, USA [10], at the University of Ottawa Blast Research Laboratory, Canada [46,50], at the testing ground of Swedish Defence Research Agency (FOI) in Marsta, Sweden [44], and at the Ernst-Mach-Institute in Freiburg, Germany [39]. Listed tubes are slightly different by their internal cross section near the test area and pressure levels exerted on test specimens but their work mode is very similar.…”

“…Usually the highspeed camera is mounted outside the shock tube and is oriented to record the motion of the specimen. If positioned perpendicular to the shock tube, it can record deflections and velocities which are determined from sequential images taken during testing [10,38,43,46,48,49,51]. Propagation of the damage pattern can also be analysed if the camera is placed in such a way to have a clear view of the specimen surface of interest.…”

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.

“…Additional Ductal panels were tested at far-range standoff distances by Ngo et al (2007), and at close range by Wu et al (2007) with similar observations. As for simulated blast tests, Ellis et al (2014) conducted experiments on four simply-supported unreinforced UHPC panels using a blast load simulator. Following the validation of a multiscale model, a parametric study showed that steel fiber properties such as volume ratio, aspect ratio and fiber packing have an important effect on increasing energy dissipation when using UHPC.…”

This paper summarizes the results from three one-way slabs which were tested under gradually increasing shockwave loads using a high-capacity shock-tube at the University of Ottawa. The series includes one control slab built with conventional concrete and two companion slabs built with ultra-high performance concrete (UHPC). Results in terms of blast resistance, control of displacements, and damage tolerance are used to study the effects of the design parameters on the performance of the panels. Overall, the results demonstrate significant benefits associated with the use of UHPC in reinforced concrete slabs tested under extreme blast pressures.

“…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.
