Abstract

Abstract: In order to study the impact-resistant performance of double-skin steel-concrete composite(SC)panel， the ABAQUS software was utilized to establish the finite element(FE)models of SC panel subjected to drop hammer impact. The accuracy of numerical models was verified by comparing the FE simulations with the test results. Based on the validated models， the influences of steel plate ratio， impact height， material strength， boundary condition and indenter shape on the dynamic responses of SC specimen were revealed. Finally， the energy method was employed to calculate the maximum mid-span deflection of SC panel. The results indicate that steel plate ratio， impact height， indenter shape and boundary condition present significant effects on the dynamic response within the parameter range of this work， and the effects are more obvious when the steel plate ratio exceeds 4%. The theoretical calculation method used in this study can reasonably predict the maximum mid-span deflection of SC panel under impact loading.
