INVESTIGATION ON IMPACT RESISTANTCE OF STEEL PLATEREINFORCED CONRETE BARRIERS AGAINST AIRCRAFT IMPACTPART 3: ANALYSES OF FULL-SCALE AIRCRAFT IMPACT

摘要

Steel plate reinforced concrete (SC) walls and slabs are structural members in which the rebars of reinforcedconcrete are replaced by steel plates. Steel plate reinforced concrete structures are more attractive structuraldesign alternatives to reinforced concrete structures, especially with thick, heavily reinforced walls and slabssuch as nuclear structures, because they enable a much shorter construction period, greater earthquake resistantand more cost effectiveness.Experimental and analytical studies performed by the authors have also shown that SC structures are muchmore effective in mitigating damage against scaled aircraft models , as described in Parts 1 and 2 of this study.The objective of Part 3 was to determine the protective capability of SC walls and roofs against a full-scaleaircraft impact by conducting numerical experiments to investigate the fracture behaviors and limit thicknessesof SC panels and to examine the effectiveness of SC panels in detail under design conditions. Furthermore, asimplified method is proposed for evaluating the localized damage induced by a full-scale engine impact.
