“…Another representative type of connector was the friction welded bar connectors in 'bi-steel' structure as shown in Figure 1(c) [4]. The friction welded connectors were proved to be effective in providing longitudinal shear and transverse shear resistance [5]. However, the equipment for the friction welding limited the thickness of the sandwich plate within 200-700 mm.…”

Steel-concrete-steel (SCS) sandwich structure with ultra-lightweight cement composite core has been developed and proposed for applications in offshore, bridge and building constructions. A new form of J-hook connector is introduced to bond the steel face plates and cement composite core to form an integrated unit which is capable of resisting extreme loads. Design formulae were proposed to predict the shear, tension, and their interaction resistances of J-hook connectors. Thirty push-out tests and eighteen tensile tests were carried out on steel-concrete-steel sandwich plates with J-hook connectors embedded in different kinds of concrete to determine their shear and tension resistance, respectively. Nonlinear finite element (FE) model was also developed to predict the load-slip and ultimate behavior of J-hook connectors under combined shear and tensile loads. Finally, the design formulae were validated by comparing the predicted results with those obtained from tests and FE analyses. The formulae may be used to evaluate the tension, shear, and shear-tension interaction resistances of the J-hook connectors in steel-concrete-steel sandwich composite structures.

“…Oduyemi and Wrigth [2], Wright et al [3] and Shanmugam and Kumar [4] carried out experimental 10 investigations on the response of conventional SCS structural members with headed shear studs subjected to static loading. Corus UK have developed the Bi-steel composite sandwich panels with transverse steel bars friction-welded to both steel faceplates simultaneously (Xie et al [5]). …”

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.
