Numerical simulation and validation of impact response of axially-restrained steel-concrete-steel sandwich panels

Journal Article


Abstract


  • Steel–concrete–steel (SCS) sandwich panels are an effective means for protecting personnel and infrastructure

    facilities from the effects of external blast and high-speed vehicle impact. In conventional

    SCS construction, the external steel plates are connected to the concrete infill by welded shear stud connectors.

    This paper describes a programme of research in which the non-composite SCS panels with axially

    restrained connections were studied experimentally and numerically. High fidelity finite element

    models for axially restrained steel–concrete–steel panels subjected to impact loading conditions were

    developed using LS-DYNA. The simulation results were validated against the dynamic testing experimental

    results. The numerical models were able to predict the initial flexural response of the panels followed

    by the tensile membrane resistance at large deformation. It was found that the strain rate effects of the

    materials and the concrete material model could have significant effect on the numerically predicted flexural

    strength and tensile membrane resistance of the panels.
