“…Design parameters, such as slab thickness, reinforcement percentage, concrete strength, and impact loading velocity, can modify the damage of the component subjected to the impact load [6,7]. The two most common failure mechanisms in concrete slabs are localized failure and punching shear failure at high-impact loads [14] and projectile loads [23,53,[65][66][67][68] at low-impact loads, producing globally dispersed fracture patterns in slabs.…”

“…The emotional reactions and failure behaviors of concrete slabs and plates under different velocities were studied under low [59,[62][63][64], moderate [43], and high [53]. Dynamic impact loads subjected to slabs have been extensively studied in the literature, using analytical [23,53,65], numerical [23,43,65,66], and experimental [14,63,67,68] methods. Typically, the two most common failure mechanisms in concrete slabs were localized failure and punching shear failure at high-impact loads [14] and projectile loads [23,53,[65][66][67][68] at low-impact loads (globally dispersed fracture patterns in slabs).…”

Concrete is brittle; hence, it is incredibly likely that concrete buildings may fail in both local and global ways under dynamic and impulsive stresses. An extensive review investigation was carried out to examine reinforced concrete (RC) slab behavior under low-velocity impact loading. Significant past research studies that dealt with experimental and numerical simulations and analytical modeling of the RC slabs under impact loading have been presented in this work. As a result, numerous attempts to define failure behavior and to assess concrete structures’ vulnerability to lateral impact loads have been made in the literature. Based on analytical, numerical, and experimental studies carried out in previous research, this article thoroughly reviewed the current state of the art regarding the responses and failure behaviors of various types of concrete structures and members subjected to low-velocity impact loading. The effects of different structural and load-related factors were examined regarding the impact strength and failure behavior of reinforced concrete slabs reinforced with various types of strengthening procedures and exposed to low-velocity impact loads. The reviews suggested that advanced composite materials, shear reinforcement, and hybrid techniques are promising for effectively strengthening concrete structures.

“…Slabs are also one of the most common structural members which are commonly used in connection with supporting beams. Many studies existing in the literature evaluating the dynamic responses, and failure behaviors of concrete slabs and plates under low- [206][207][208][209][210][211][212], moderate- [213] and high-rate [214] impact loads analytically [214][215][216], numerically [213,215,[217][218][219], experimentally [22,208,211,218,220,221].

Reinforced concrete structures and structural members used in strategic infrastructures such as highway bridges, high-rise buildings, etc. are inherently subjected to lateral impact loads arising from the collision of vehicles, vessels, falling rocks, and rigid objects having different impact geometries, weights, and velocities. Due to the brittle nature of concrete materials, both localized and overall failure modes are very likely to occur in concrete structures under dynamic and impulsive loads. Hence, many attempts have been carried out in the literature to recognize the failure behaviors and to assess the vulnerability of concrete structure under lateral impact loads. This paper presents a comprehensive state-of-the-art review on the responses and failure behaviors of various types of concrete structures and structural members subjected to lateral impact loads based on analytical, numerical, and experimental studies carried out by the previous research works. In addition, the influences of various structural- and load-related parameters on the impact resistance and failure behaviors of different concrete structures under lateral impact loads are reviewed.

Impact-loaded concrete structures cause severe and rapid damage, resulting in significant property and human life loss. As the temperature rises, the damage caused by impact loading becomes increasingly severe. Concrete structures need structural health monitoring (SHM) to avoid these damage and loss. In this study the voltage relation technique were used to identify the damage state of concrete under impact loads at various temperatures conditions as experimentally and numerically. For this purpose, an experimental study was performed on concrete cube specimens in which different piezo configurations (surface bonded, non-bonded, and jacketed) were installed to acquire the voltage data. Before applying an impact load to the top surface of concrete specimen, it was preheated at 50 oC, 100 oC, and 150 oC to provide the temperature effect, and then a free-falling iron ball was dropped from 3 m heights on the top of the specimens. Furthermore, finite element analysis has been carried out to validate the experimental results with analytical results. The experimental results shows that the voltage relation technique are well capable in detecting the damage in concrete under the temperature and impact loading conditions. All the piezo sensors configurations are capable in finding the damage. Jacketed sensors are more efficient in health assessment of concrete in terms of voltage relations. In terms of strain values, the analytical results are in good agreement with the experimental results.
