Based on test results, the effect of a steel liner on both scabbing and perfo- ration was evaluated quantitatively by converting steel liner with a certain thickness into the equivalent concrete thickness. And how to improve the impact resistance of double-layered RC panels is discussed. INTRODUCTION The establishment of a design method f
