ABSTRACT
Steel-concrete-steel (SCS) panels are an effective means for protecting critical infrastructure facilities from the effects of external detonations. Existing designs of SCS panels utilise composite action between the core concrete and the external steel faceplates which requires mechanical or adhesive connections. Remennikov et al. (2010) experimentally investigated the static and impact performance of noncomposite SCS panels in which no shear connectors were used to connect the steel faceplates and the concrete core. High effectiveness in resisting blast and impact loads is achieved through special detailing of the flared end connections that provide axial fixity as well as restraining the relative movement between the concrete core and the external steel plates.
