| Abstract | ||||
| Double skin composite (DSC) is a structural system of steel plates connected to a sandwiched concrete core with welded stud shear connectors. Shear studs are welded to the plates at regular centers and act as connectors for the concrete core. The final structure acts compositely with the steel skins carrying either tension or compression, the concrete core carrying some compression and the connectors transferring both horizontal shear between layers and vertical shear across the section. In this research an investigation of double skin composite panels behavior when subjected to quasi-static loading was done. A series of quasi-static tests were used to analysis deformation and energy absorption capacity of such system when perforated by rigid penetrator with conical nose shape. Research results showed that such elements are very effective in resisting quasi-static loads and have great ability of absorbing energy when subjected to perforation due to ductility of lower plate skin and vertical stiffness of lower shear studs. | ||||
