“…This demonstrates that the friction losses occurring in the drop‐weight test setup can be neglected and the test setup can apply impact loads with identical input impact energies. The negligible differences that occurred in the impact loads measured from RC slabs subjected to identical input impact energy stem from the different strength and stiffness values of RC slabs 4,5,7,12,16,18,19,22,23 …”

“…Furthermore, the studies focused on the impact behavior of RC slabs strengthened using fiber reinforced polymer (FRP) material with various layouts, the pretensioned RC slabs, and the slabs manufactured from fiber‐RC have been presented in the literature 1–18 . However, the number of experimental studies examining the effects of different support conditions on the behavior of RC slabs subjected to impact loading is quite limited 19 …”

“…At the end of the literature review, authors have encountered only one study in which the effect of the support conditions on the impact behavior of RC slabs. In this experimental study conducted by Anil et al, 19 eight identical RC slabs with different support types and support layouts were tested under the effect of impact load using a drop‐weight test setup. Under the impact loading, the effect of the support types and the support layouts on damage pattern, the number of drops causing the failure, dynamic responses such as acceleration, velocity, and displacement measured from the RC slabs has been investigated.…”

Reinforced concrete (RC) slabs may be subjected to impulsive dynamic loads such as blast and impact during their service period. Many studies related to the impact behavior of RC slabs have been presented. However, comprehensive studies where the effect of the support conditions on the impact behavior of RC slabs has been investigated are still limited. Thus, this study has focused on the effects of the support types and the support layouts on the dynamic responses and the failure modes of RC slabs subjected to impact loads. In the first part of the study, 9 two‐way RC slabs with various support layouts composed of fixed and hinged supports were tested under impact load via the drop‐weight test setup. Two different input impact energies were transmitted to RC slabs during impact loading. The time histories of the accelerations and displacements occurred in RC slabs, and the impact loads acting on RC slabs were recorded. The crack patterns due to the impact load were observed. The dynamic responses obtained by experiments have been interpreted in detail. In the second part, a detailed finite element procedure in which explicit dynamic analysis is performed has been introduced for verification of the experimental results. Good agreement between the experimental and the numerical results has been demonstrated. It has been concluded that proposed finite element procedures can be used for evaluation of the dynamic responses and failure modes of RC slabs under low‐velocity impact load.

“…The experimental study was conducted using an impact tests setup designed to test the reduced scale test specimens. The test setup used in the experimental study was used many times in the test of similar test specimens . The test setup itself allows weights of varying magnitudes to be dropped from a maximum height of 2,500 mm onto test specimens of varying dimensions.…”

In this study, the flexural strength and the impact behavior of the glass fiber composite plates with the same mesh and layer geometry and the effect of the addition of nanographene (GNP) at various ratios into the matrix were experimentally investigated. The variable examined in the study is the percentage of the nanographene that added in the matrix of glass fiber composite plates. In this study, six types of glass fiber plates were produced; with no nanographene added reference specimen, and with the ratio of 0.15, 0.25, 0.35, 0.45, and 0.70% nanographene added specimens. The effect of nanographene addition to the epoxy matrix on the flexural strength and impact behavior of the specimens was investigated by applying a three‐point bending test and a constant‐energy impact load with the free‐weight test method on the glass fiber plate specimens. The highest flexural strength was observed at the 0.25% nanographene added specimen. Further addition of the nanoparticle caused the flexural strength to decrease. In the free weight drop impact test, the highest acceleration and lowest displacement were found at the 0.25% nanographene added specimen. Adding more nanoparticles adversely affected the impact behavior. The optimum nanographene ratio was determined to be 0.25%. POLYM. ENG.

Reinforced concrete (RC) members may expose to impulsive dynamic loads due to the reasons such as the explosions occurring in the interior or exterior part of them, rockfall, the vehicle crash to the bridges, the collision of masses with the effects of floods and landslide. Many studies have investigated the effects of impulsive dynamic loads on the beam, column, and slab RC structural elements have been investigated in the literature. However, the authors have not encountered any study focused on the impact behavior of beam to column connections of the frames constructing the bearing system of reinforced concrete structures. Therefore, an experimental study has been planned to investigate RC beam impact behavior to column connections strengthened with carbon fiber‐reinforced polymer (CFRP) strips. The concrete compressive strength, shear reinforcement spacing, CFRP strip spacing, and input impact energy applied to test specimens were taken as experimental variables. The time histories of impact load acting on test specimens, accelerations, displacements, and the strains measured from CFRP strips have been recorded in experiments. The experimental variables' effect on dynamic responses of RC beam to column connections strengthened with CFRP strips subjected to impact load has been interpreted in detail. The study's scope and improved numerical analysis procedure have also been introduced to verify experimental results. Good agreement between numerical and experimental results demonstrated that the presented numerical procedures could be safely used for evaluation of impact behavior of RC beam to column connections strengthened with CFRP strips.
