Abstract
Abstract. In order to avoid the damage of precision guided weapons on target, a steel fiber reinforced concrete sandwich structure with different types of support was proposed. The failure characteristics of penetration plate, steel fiber reinforced concrete plate and support beam were studied by contact explosion test. The results showed that the using of steel fiber sheet sandwich structure could increase a resistance level for the project with the same thickness of the protective layer. The failure mode of steel fiber reinforced concrete sandwich structure under partial blast loading was still the local damage mode, the strength and thickness of steel fiber laminate material, height and spacing of support beam were the main factors to control the effect of wave attenuation in steel fiber reinforced concrete sandwich structure, if some measures to prevent vibration on steel fiber sheet or under-surface of vault would enhance the resistance of structure.
