Basic Characteristics of High-Speed Fragments upon Perforation of Reinforced Concrete Slab
Publication: Journal of Performance of Constructed Facilities
Volume 34, Issue 6
Abstract
Based on advanced numerical simulation technology, a complex finite-element model of a fragment and slab is constructed using software LS-DYNA version 971. A series of numerical simulation analyses are conducted on this model to estimate the basic characteristics of high-speed fragments on the perforation of the reinforced concrete slab. First, the process by which the fragments penetrate the slab is analyzed in detail. Subsequently, the effects of a few parameters, such as floor load, compressive strength of concrete, and fragment shape, on the penetration depth of the fragment are further investigated. Moreover, the relation between the residual and striking velocities of the fragment is improved considering the fragment shape. Finally, the basic steps to predict the residual kinetic energy of the fragment are presented. Results show that penetration depth and residual velocity are significantly affected by fragment end shape, and increase significantly with fragment end shape coefficient. The analysis is rigorous and comprehensive, and the results are true and reliable; furthermore, it indicates that the proposed method can accurately and effectively predict the residual kinetic energy.
