Modeling and Analysis of Concrete-Filled Steel Structure Under Aircraft Impact

Concrete-filled steel structures (SC), or called steel concrete composite structures are composed of steel plates and reinforced concrete. This kind of structures has demonstrated more effective against blast and impact loads, and has been used in risk-sensitive structures such as the nuclear electric power plant and other critical constructions. The comprehensive modeling and analysis is performed in this paper for the full scale SC panel against aircraft impact after the testing results of 1/7.5 scaled model was reviewed and correlated. The methodology, modeling approach, and mesh density sensitivity investigation is presented.Copyright © 2011 by ASME
