“…The general analysis of blast-loaded metal sheets is available within different publications. Application examples can be found within the design of containment rooms for package handling on airports or harbors (Crawford, 2006) or general analytical formulations (U S Army, 2008). The blast resistance of cold-formed steel components can be analyzed with the use of SDOF models (Crawford, 2006), but no detailed information is given concerning the modeling of the resistance behavior with assumed bending of the investigated structure.…”

The response of sandwich panels composed of thin face skins and corrugated cores is investigated through an empirical study by varying the stand-off distance and material properties for close-in detonations (Zhang et al, 2015).…”

Blast loading scenarios and the corresponding hazards have to be evaluated for infrastructure elements and buildings especially at industrial sites for safety and security issues. Point fixed corrugated metal sheets are often applied as façade elements and can become a hazard for humans if they are pulled off. This paper investigates the dynamic bearing capacity of such structural members in terms of their general bending behavior in the middle of the span and pull-out behaviors at the fixing points. The elements are fixed at two sides and the load transfer is uniaxial. An experimental series with static and dynamic tests forms the basis to identify the predominant failure modes and to quantify the maximum stress values that can be absorbed until the investigated structural members fail. The experimental findings are applied to create and to optimize an engineering model for the fast and effective assessment of the structural response. The aim is the derivation of a validated model which is capable to predict the blast loading behavior of metal sheets including arbitrary dimensions, material properties, and screw connections. Results of this study can be integrated into a systematic risk and resilience management process to assess expected damage effects and the evaluation of robustness.

“…So far, barrier walls, such as reinforced concrete wall, steel–concrete–steel (sandwich) wall, bi-steel wall and those made from concrete masonry units, thin concrete pre-cast panels, soil and water, are found in the literature (Crawford and Lan, 2006; Lin et al, 2014; Rose et al, 1998; Smith, 2010). Blast resistance of the panels made from ultra-high-performance concrete, ultra-high-performance fibre-reinforced concrete and reinforced ultra-high-performance fibre-reinforced concrete was also investigated (Cavill and Rebentrost, 2006; Ngo et al, 2007; Wu et al, 2009).…”

In this study, a three-dimensional finite element model is developed to investigate the pressure-impulse response of the steel plates with semi-rigid connections under blast loads. The strain rate effect on the material properties is considered, and a number of spring elements are used for simulating the plate to support connections. Once verified, the developed finite element model is then used to investigate the effects of a series of parameters on the blast resistance and energy absorption capability of the steel plates, including the effects of connection rigidity, plate thickness, impulse loading and the shape of corrugation.

“…The steelconcrete-steel (SCS) composite walls consist of a thick concrete core confined by two relatively thin steel faceplates. Crawford and Lan [3] presented the design concepts of axially restrained noncomposite SCS panels for resisting blast loading and provided experimental verification for the fullscale blast wall. Remennikov et al [4,5] investigated experimentally the static and impact performance of non-composite SCS panels in which no shear connectors were utilised to connect the steel faceplates and the concrete core.…”

Non-composite steel-concrete-steel panels develop high load-carrying capacity through the tensile membrane resistance of the steel faceplates at large displacement. The response of a full-scale barrier structure composed of the non-composite SCS panels and steel posts under various blast loading scenarios was investigated using non-linear finite element software LS-Dyna. The simulation results showed that the barrier was able to withstand very large blast energy. It can be concluded that non-composite SCS panels can provide an attractive solution to expedite construction of high-performance protective barriers to resist extreme blast loadings.
