Abstract

Analysis of joint motion of building structure and crashing missile impacting it is described. The missiles of this kind may be generated by various natural and man induced events. Equations of motion are derived. Example of their application to the problem of successive perforation of several walls by crushing missile is given. It demonstrates that the methodology permits to take into account more accurately distribution of the missile kinetic energy between itself crashing and impacted building structure deformation. The methodology described may be used for safety analysis of nuclear power plants, civil defense and so on structures subjected to destructible large kinetic energy missiles impacts.
