“…The SHPB machine was used to perform the dynamic test at strain rates between 30.09 and 102.48 s −1 as shown in Figure 2 [46,47]. The machine bars were manufactured from a stainless steel material with a diameter of 50 mm which was selected to reduce the wave dispersion and increase the accuracy of the recorded signals [46]. A hand grinder was used to decrease and achieve good contact between the bars and concrete samples.…”

“…A hand grinder was used to decrease and achieve good contact between the bars and concrete samples. Moreover, an alignment by a laser with a precision reached up to 0.01 mm was used to accomplish a good coaxial and fulfil the force equilibrium condition [46]. The average dynamic strength of five cylindrical samples (350 samples) for both concrete was recorded at each exposing temperature and curing age.…”

“…The average static compressive strength of three cubic samples for both concrete was recorded at curing ages of 7, 28 and 90 days within room temperatures of 400 and 700 • C according to British standards by using a compression machine with a maximum load capacity of 5000 kN [45].

“…In the current study, cylinder specimens with a ratio of length to the diameter of 1 were used during the dynamic test. Davies and Hunter [48] indicated that there is no clear influence for the size of a concrete cylinder sample if its length to diameter ratio kept within 0.31 to 1.55 [46,47]. Besides, Lindholm [49] reported that the length of concrete specimens should be short enough to achieve a uniform state of stress throughout the test.…”

The dynamic behaviour of high-volume fly ash concrete with nano-silica (HVFANS) and polypropylene fibres at curing ages of 7 to 90 days was determined by using a split Hopkinson pressure bar (SHPB) machine. At each curing age, the concrete samples were laboratory tested at different temperatures conditions under strain rates reached up to 101.42 s−1. At room temperature, the results indicated that the dynamic compressive strength of plain concrete (PC) was slightly higher than HVFANS concrete at early curing ages of 7 and 28 days, however, a considerable improvement in the strength of HVFANS concrete was noted at a curing age of 90 days and recorded greater values than PC owing to the increase of fly ash reactivity. At elevated temperatures, the HVFANS concrete revealed a superior behaviour than PC even at early ages in terms of dynamic compressive strength, critical strain, damage and toughness due to increase of nano-silica (NS) activity during the heating process. Furthermore, equations were suggested to estimate the dynamic increase factor (DIF) of both concretes under the investigated factors.

Recently, the multiscale hybrid fiber reinforced cementitious composites (MSHyFRCC) with steel fibers, polyvinyl alcohol (PVA) fibers, and calcium carbonate whiskers had developed with improved mechanical properties under static load. Although, there is still a research gap to study its behavior and properties under the action of earthquake load. In this work, the properties of steel fibers, PVA fibers, and calcium carbonate whisker hybrid FRCC are evaluated by using single degree of freedom hydraulic shaking table. A total of 10 mixes having different mix proportions, fiber lengths, and contents of steel fibers, PVA fibers, and calcium carbonate whiskers are considered. The stress–strain curves, failure mode of cubes, compressive strength, peak micro‐strain, strain energy density, failure mode of column specimen, displacement‐time curves, strain‐time curves, and top acceleration‐time curves are studied. The multiscale hybrid fibers offer resistances against crack growth under dynamic load which results in longer time period with improved displacement, strain, and acceleration. The 1.5% steel fibers of 13 mm, 0.75% PVA fibers of 6 mm with 1% calcium carbonate whiskers and 1.25% steel fibers of 35 mm, 0.55% PVA fibers of 12 mm with 2% calcium carbonate whiskers are proposed to be the optimized mixes for short‐ and long‐length hybrid fibers, respectively.
