Sažetak

This study presents a design approach for 50 mm thick prefabricated composite concrete panels capable of withstanding blast pressures from C4-type explosives applied to their surfaces. The composite panel consists of a high-strength concrete core that is shear-bonded and positioned between two steel plates. The designed panel provides three-stage blast resistance against multiple explosions, leveraging its composite structural qualities, including bending resistance, catenary resistance, and sacrificial resistance, which are achieved through the contained fracture and plastification of its material components. This study introduces the principle of “Design for Multiple Intrinsic Resistance” (DeMIR) and discusses the results of blast load tests performed on the designed panels, involving four separate explosions generated by C4 explosives.
