The missile-target interaction method is used to perform simulations of the impact of a commercial B767 aircraft on a shield building made of steel-concrete-steel sandwich panels to study impact damage characteristics. Refined finite element models of a shield building and two large commercial B767 aircraft are developed. The aircraft impact force is given and assessed with the Riera function to verify the B767 aircraft model, and a simulation analysis of tests is performed to verify the concrete model. The peak impact forces of the fuselage, engine, wing, and entire aircraft are approximately linearly proportional to the square of each impact velocity. The shield building subjected to the aircraft impact exhibits no perforation, and the damage range of the shield building expands with increasing impact velocity. The influences of impact velocity, aircraft mass, impact angle, and tie bar diameter on the deformation of the shield building are significant. The thickness of the steel plate plays an important part in the deformation of the shield building, whereas the compressive strength of concrete and the water in circular tank have only a slight effect on the deformation of the shield building.

“…Concrete is a common material for modern buildings and fortifcations, and its excellent strength and plasticity have become the frst choice for various man-made fortifcations [2]. Te large caliber penetrator, represented by the ground-penetrating projectile, usually deals with the largethickness of concrete fortifcation [3], while the antiexplosive projectile has a good destructive efect on the concrete wall with fnite thickness [4].…”

“…At present, a large number of experts and scholars have carried out various types of penetration tests on concrete, and the concrete model parameters in the simulation are compared [5]. In reference [2], the experiment and numerical simulation of missile penetration into the reinforced concrete target plate are compared, and the simulation model can well describe the damage mechanism of the structure, and it also introduced the calculation method of low strength concrete penetration depth, and the calculation formula of the residual velocity was also introduced [6]. Te damage characteristics of projectiles with diferent head shapes penetrating the concrete are studied, and the relationship between the back damage of the target plate and the shape of the warhead is analyzed [7].…”

In order to study the joint damage mechanism of multiple prefabricated fragments to finite thickness concrete targets, experiments on the damaging effect of a single fragment on a 300 × 300 × 100 mm concrete target were carried out, and the reliability of the simulation calculation model of single fragment damage to concrete was verified. On this basis, according to the trajectory of two fragments penetrating concrete, the double fragment penetration is divided into two penetration situations, that is, coplanar and heterogeneous. The orthogonal optimization method is used to carry out the joint damage simulation calculation of the double fragments to the concrete target by changing the fragment velocity, penetration angle, fragment spacing, and other factors. The simulation results show that the relationship between joint damage and fragment spacing is the largest when the fragment trajectories are coplanar, and the partial least squares regression coefficients affecting the joint damage time and surface joint length are 0.70 and 0.68 respectively. When the trajectory is different, the joint damage mode is relatively complex. Based on this, the joint damage degree analysis method between fragments is established, and each variable can explain 73.8% of the joint damage degree. It is found that the joint damage of the front pit area is the largest when the fragment is in different planes, and the PLS regression coefficient is −0.44. The hypothesis that joint damage is easy to occur in the area of the intersection line on the back of the target is analyzed and verified.

“…Assessment of risks associated with these localised phenomena deserves separate treatment and is outside the scope of considerations of the article. Some relevant experimental investigations were carried out and reported by authors such as Dancygier et al (2007), Heckötter and Vepsä (2015), Kojima (1991), Zhang et al (2005). These experiments normally involved the use of gas gun or gun powder to fire the impactor.…”

Experimental and Analytical Assessment of Flexural Behavior of Cantilevered RC Walls Subjected to Impact Actions

et al. 2020

Reinforced concrete (RC) impact-resistance barriers, such as rockfall barriers, often consist of a cantilever RC wall, which is expected to experience flexural bending under impact loading to resist the associated design actions. In order to investigate the flexural response behaviour of an RC cantilever wall, a large-scale experiment was carried out on a fixed base RC cantilevered barrier wall measured 1.5 m in height, 3 m in length and 0.23 m in thickness. Two "torpedo" shaped steel impactors with mass of 280 kg and 435 kg were released from controlled heights ranging from 0.2 m to 1.4 m in pendulum style to strike the top of the wall. The first half of this paper presents an overview, findings and results of this large-scale, original experimental work. The second half of the paper presents a displacement-based analytical model, which can be used to assess and determine important design parameters for cantilever RC barrier walls of this nature; including, deflection demand and material strains. Systematic comparisons of the experimental results and the proposed analytical model demonstrate the accuracy and reliability of the proposed model for assessing cantilevered RC barrier walls subject to impact actions.
