Steel–Concrete-Steel Sandwich Panel Under Simulated Blast Loading
The performance of non-composite steel–concrete-steel (SCS) sandwich panels under simulated blast loading was experimentally and numerically studied. Two SCS sandwich panels with different concrete depths were tested, and the simulated blast loading was applied by utilizing an inflated airbag to transmit the impact force from the dropped hammer onto the panels in the form of uniform pressure loading. The deformation modes, applied pressures, displacement and strain responses of the panels were obtained from the tests. A combination of flexure and shear deformation mode was observed for the SCS panel with thinner concrete core while there was minimal visible deformation for the thicker panel. The maximum and permanent deformations of the panel with thicker concrete were significantly reduced owing to the increase in resistance and mass. Debonding between concrete core and bottom plate was also observed for the tested panels. Following the test, Finite Element (FE) models were established and verified against the test data. It was shown in the FE analysis that the steel plates dissipated more energy owing to its higher strength and ductility as compared to the concrete core.
