“…Wu studied the dynamic response of reinforced concrete slab-buffer layer composite structure under rockfall impact and analyzed the influence of different impact velocities and buffer layer thickness on the damage of reinforced concrete slab [10]. Hossain et al [11] conducted an in-plane impact test and finite element analysis on the new composite wall (filled with two layers of the profiled steel plate and one layer of concrete). e results showed that, through repeated impact tests, the finite element model could accurately predict the maximum horizontal displacement and maximum acceleration at the top of the wall.…”

In order to study the impact resistance of civil air defense engineering shear wall, the impact resistance of civil air defense engineering shear wall was studied by combining finite element numerical simulation with pendulum impact test. The effects of impact height, pendulum mass, and impact times on the impact resistance of civil air defense engineering shear walls were analyzed. It was shown that when the impact height increased from 0.4 m to 2.5 m, the failure mode of civil air defense engineering shear wall tended to be local impact failure, and the horizontal displacement in the middle of the wall span increased. The concrete crushing occurred in the impact area of the back of the civil air defense engineering shear wall. The increase in the impact height is a negative factor for the impact resistance of the civil air defense engineering shear wall. With the increase of pendulum weight, the number of concrete horizontal cracks in the back of the civil air defense engineering shear wall increased, while the number of vertical cracks decreased, but the impact surface was destroyed. Through multiple impact tests on the civil air defense engineering shear wall, the civil air defense engineering shear wall had accumulated damage. The longitudinally loaded steel on the back reached the ultimate strength, and there are large cracks at the bottom and even collapses. The increase of impact times has a great influence on the impact resistance of the civil air defense engineering shear wall. Through the analysis of the factors affecting the impact resistance of civil air defense engineering shear wall, it provides guidance for civil air defense engineering shear wall to resist impact load.

“…1 Hence, in the recent years, many researchers have focused on the designing of different patterns for the core of sandwich panels with the skins made of laminated composites. 2-21 For instance, Ji et al 5 proposed a hybrid sandwich panel consisting of hollow metallic grid reinforced epoxy system as the core and glass/vinyl ester laminates as the face sheets. The specimens were tested under low-velocity and ballistic impact testing.…”

In this paper, the impact response of bi-directional corrugated core sandwich structures was investigated. The core and skins were made of E-glass/epoxy laminated composites. Additive manufacturing technology was used to print the molds applied to fabricate the cores. The influence of different periods, i.e. T = 30, 37.5, 50 and 75 mm, of the double-cosine corrugated core on the impact response of the panels was evaluated. In addition, some other panels with regular corrugated cores were manufactured to evaluate the impact response of the bi-directional corrugated core structures. A finite element modeling was also carried out to analyze the impact behavior of the samples. The empirical measurements and the numerical predictions showed that the panels with the bi-directional corrugated core have a significant improvement in the absorbed energy under impact loading at each given period. It was also manifested that the panel consisting of the bi-directional corrugated core with T = 37.5 mm has the highest specific energy absorption.

“…Hu et al studied the deformation capacity of concrete‐filled steel plate composite shear walls, and an analysis program of analyzing their moment‐curvature behavior was developed. Hossain et al investigated the impact shear resistance characteristics of double skin composite wall using finite element model, such as impact energy dissipation, fundamental period, and stress–strain development. Due to the lack of predicting the structural performance as the structure approaches collapse, the hysteretic models of composite shear walls were developed by Wei et al and Zhao et al A closed‐form solution based on partial interaction theory was deduced by Sabouri‐Ghomi et al to analysis composite shear wall considering pure out‐of‐plane loading.…”

Summary Two types of prefabricated composite shear wall systems were proposed using modular and separated dry‐assembled ways, respectively. The seismic performance of four composite shear wall systems, two for the modular assembly way and two for the separated assembly way, was numerically evaluated including failure mode, loading and deformation capacities, hysteresis behavior, ductility, stiffness degradation, and energy dissipation. The nonlinear numerical simulations were conducted based on plastic‐damage constitutive laws for both concrete and steel materials using ABAQUS platform, which were further verified by the experimental investigations. The results showed that the mechanical performance of the modular assembly system is superior than that of the separated assembly system. The former exhibited good bearing and deformation capacities: The peak force is enhanced by 50% on average, the ultimate drift ratio reaches an average value of 3.7%, and the ductility coefficient has an average value of 10.5. As for the same assembly way, the prefabricated system with inner steel plate appeared better seismic properties compared to that with outer steel plate. Furthermore, the modular assembly system behaved prominent energy dissipation capacity with plentiful hysteresis loops. The equivalent damping ratio of this system reaches 15.93% at the drift ratio of 2%, which is the limit drift ratio for normal buildings in rare earthquakes.
