The response of axially restrained non-composite steel–concrete–steel sandwich panels due to large impact loading

Abstract

In conventional steel-concrete-steel (SCS) construction, the external steel plates are connected to the concrete infill by welded shear stud connectors. This paper describes a programme of experimental and numerical investigations on reduced-scale non-composite SCS panels with axially restrained connections. The experimental results have demonstrated that the non-composite SCS panels are capable of developing enhanced load-carrying capacity through the tensile membrane resistance of the steel faceplates. This type of construction was found to exhibit highly ductile response and be able to sustain large end rotations of up to 18° without collapse. High fidelity finite element models for SCS panels under impact loading conditions were developed and the simulation results were validated against the experimental data. With the validated FE models, a full-scale barrier structure composed of the non-composite SCS panels and steel posts was subjected to a head-on collision by the Ford F800 single unit truck. The simulation results showed that the non-composite SCS barrier construction is able to resist very large impact energy and effectively terminate the fast moving vehicle. The axially restrained non-composite SCS panels were found to provide an effective means for protecting assets against severe impact attacks. © 2012 Elsevier Ltd.

Finite element modeling of impact shear resistance of double skin composite wall

“…Experimental and numerical investigations were conducted to study the impact resistance of non-composite steel-concrete-steel (SCS) sandwich panels with axially restrained connections [28,29]. SCS panels demonstrated enhanced load-carrying capacity exhibiting highly ductile response allowing large end rotations of up to 18°without collapse.…”

Performance Study of Sc Wall Based on Experiment and Parametric Analysis

“…Over the past thirty years, extensive research and development work on the design, analysis, testing and mechanical behavior of SC walls on the basis of previous research has been done in China, the United States, South Korea, the United Kingdom and Japan (Huang & Liew, 2016;Ji et al, 2013;Link & Elwi, 1995;Kim et al, 2009;Oduyemi & Wright, 1989;Ozaki et al, 2004). SC wall experiments have focused on in-plane shear loading (Anwar & Wright, 2004;Ozaki et al, 2004;Eom et al, 2009;Epackachi et al, 2013Epackachi et al, , 2015aVarma et al, 2014;Kurt et al, 2016;Seo et al, 2016), out-of-plane shear loading (Hong et al, 2010;Sener et al, 2013;Varma et al, 2014), axial compression loading (Fukumoto et al, 1987;Usami et al, 1995;Takeuchi et al, 1998;Wright, 1998;Choi & Han, 2009;Zhang et al, 2014;Huang & Liew, 2016), impact loading (Remennikov et al, 2013;Sohel & Liew, 2014;Zhao & Guo, 2018), and analysis and design for combined thermal and mechanical loading (Booth et al, 2007;Varma et al, 2009Varma et al, , 2011aEom et al, 2009;Epackachi et al, 2013Epackachi et al, , 2015a, and Kurt et al (2016) tested SC walls under cyclic lateral loading to investigate the load-carrying capacity, ductility, and the effects of varying wall type, wall thickness, cross-sectional shape, reinforcement ratio, stud spacing, tie bar spacing, and strengthening methods at the wa...…”

The development and ballistic performance of protective steel-concrete composite barriers against hypervelocity impacts by explosively formed projectiles

“…Performance of steel tubular structures and panels filled with concrete as protective structures have been studied by Remennikov et al [10,11]. Remennikov and Uy [10] experimentally investigated the failure modes of concrete-filled steel tubular elements due to contact and near-field detonation of TNT charges.…”

“…Remennikov and Uy [10] experimentally investigated the failure modes of concrete-filled steel tubular elements due to contact and near-field detonation of TNT charges. Remennikov et al [11] carried out an investigation into the response of axially restrained non-composite steel-concrete-steel (SCS) sandwich panels subjected to blast and impact loads, and demonstrated the high effectiveness of steel-concrete sandwich panels as protective barriers against high-speed vehicle impacts and close-range blasts. Ngo et al [12] carried out a comprehensive, nonlinear three-dimensional numerical analysis the concrete-filled square tubular columns subjected to blast loading due to close range detonation of the TNT charges and highlighted the beneficial effect of concrete as an infill material in protective composite structures.…”
