“…Their research spans from the numerical simulation of steel columns under impact to the assessment of energy absorption in dimpled steel sheets and the analysis of impact resistance in steel parking structure columns. For non-metallic components, Bambach et al [9], Wang et al [10], Goswami et al [11], Lee et al [12], Li et al [13], and Li et al [14] have provided valuable insights. Their work includes the exploration of concrete-filled steel beams, ULCC-filled pipe-in-pipe composites, concrete slab shear failure, steel plate-concrete composite walls, and the dynamic performance of concrete beams, among others.…”

This paper focuses on the response of reticulated shell structures under oblique impact loads, with a departure from the traditional emphasis on vertical impact loads. These structures are typically utilised in large-span spaces such as iconic buildings and large venues. The study begins by establishing a numerical simulation method for reticulated shell structures subjected to oblique impact loads, which is then validated against existing experimental results. Building on this verified method, the research delves into the effects of varying impactor mass, velocity, and initial kinetic energy on the reticulated shell structure under oblique impacts, as well as the influence of different oblique impact angles. The study extensively examines the failure modes of the structure, node displacements in the structure, and variations in member stress under different impactor parameters. It further investigates how these parameters influence the maximum impact bearing capacity, impact duration, energy dissipation capability, and response forms of the structures, analyzing the reasons behind these effects. The findings offer valuable insights for further research and practical engineering design of reticulated shell structures.

“…In addition, the research field of the impact resistance of composite walls is gradually attracting more attention. Scholars at home and abroad have carried out a series of work in the field of impact [6][7][8][9][10][11]. However, there are few studies on the impact resistance of composite walls under low-speed impact and the variation law of impact force.…”

Analytical Research on the Impact Test of Light Steel Keel and Lightweight Concrete of Composite Wall

In order to study the impact resistance of light steel keel and lightweight concrete of composite walls (LSKLCW) under low-velocity impact, four composite wall specimens were designed to conduct dynamic simulation impact tests, and the failure mode, time-history curves of strain and displacement were analyzed and studied using test equipment and a loading system. The results show that the failure characteristics of the composite wall sample were elastic–plastic. Moreover, the vertical displacement and strain at the most unfavorable collision point were linearly related to the impingement height. Furthermore, the capacity of the composite wall (such as crack resistance, elastic–plastic deformation and energy dissipation) was affected by the concrete strength and the arrangement of the light steel netting. In addition, the impact resistance of the wall was significantly improved when the concrete strength was enhanced and the light steel netting was installed. Lastly, the test results were fitted and verified through the impact force calculation model of the composite wall, and then the accuracy of the test model was analyzed. The certain experimental basis and theoretical analysis basis for the impact resistance research of the composite wall can be provided by these research results.
