“…As aforementioned, flexural waves emanate from the plate boundary and propagate towards the plate center [19]. Thanks to the development of innovative material technologies, different kinds of composite lightweight structures have also been investigated [20][21][22][23] under impact loads. Unlike the previous unconfined blast situation, a confined blast (CB) means that an explosion occurs within a cabin structure, which limits the propagation of the blast wave.…”

Thin-walled metal plates and cabin structures are widely found in ships and cargos which are susceptible to attacks or accidental explosions. The present work focuses on the dynamic response mechanism of steel plates under unconfined and confined blast loads. In the experiment, digital image correlation (DIC) technique was applied to record and analyze the dynamic response process of a large-scale field blast test. The DIC measured curve and the numerically calculated curves agree well in both trends and peak values. Then, the dynamic response mechanisms of steel plates under an unconfined blast (UB) load and confined blast (CB) load were compared and discussed. The results show that the dynamic response of plates can be divided into three phases under both UB and CB loads, with different mechanisms. In phase I, plastic hinges start from the center and move to the boundary in the UB condition, while in the case of CB, plastic hinges occur close to the boundary and move in the opposite direction. In phase II, two plastic hinge lines propagate towards each other, a platform exists between the boundary, and the central area remains undeformed in the UB condition, while in the CB condition, larger deformation occurs in the peripheral region rather than the central area.

“…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.

“…SPSWs are appropriate for either the construction of new steel or concrete structures or the seismic retrofitting of existing ones. The technique is anticipated to be less expensive than concrete shear walls because foundation costs will be decreased, the amount of rentable floor surface will be enhanced, and only one trade will be required on the construction site (Khaloo et al, 2021;Kim et al, 2021;Kordzangeneh et al, 2021). When an unstiffened steel shear wall is used, the creation of an SPSW core is a process that is considered to be quite simple.…”

Steel plate shear walls (SPSWs) are a robust lateral load resistance structure because of their high ductility and efficient energy dissipation when subjected to seismic loads. This research investigates the seismic performance of an innovative infill web strip (IWS-SPSW) and a typical unstiffened steel plate shear wall (USPSW). As a result, two 1:3 scale specimens of an IWS-SPSW and USPSW with a single story and a single bay were built and subjected to a cyclic lateral loading methodology. In the prototype, semi-rigid end-plate connectors for the beam-to-column connections were utilized. The test result of IWS-SPSW showed outstanding ductility and shear load-bearing capacity without cracks or damage. Additionally, the IWS-SPSW exhibited strong energy dissipation without substantial beam-column connection distortion. USPSW showed excellent shear load-bearing capacity, low ductility, extensive infill plate corner tearing, and large infill web plate cracks. The FE models were developed and verified against experimental data. It has been shown that the infill web strips can affect the high performance and overall energy dissipation of an SPSW system. In addition, a parametric study was conducted to investigate the infill web strip material properties, such as steel strength and thickness, that can significantly enhance the system’s seismic performances.
