Abstract

Abstract

Actions of hoop steel-bar, portrait steel-bar, and steel plate on perforation block in RCBSP are discussed. According to the deformation and failure of RCBSP and distribution of energy in time and space, deformation and failure models of RCBSP are established. In addition, resistance formulae of hoop reinforcing steel bar and steel plate to projectile are deduced, and by regarding the reinforcing steel bar net as an equivalent steel plate, the motion equations of projectile and perforation block are proposed. The acceleration, speed, and displacement of projectile in concrete are compared with those in BCBSP, showing the influence of the elements in RCBSP on projectile's displacement field.
