Abstract

Dynamic response analysis of a special airtight anti-fire door for nuclear power plant subjected to the combined action of tornado and windborne debris impact was conducted by using the software LS-DYNA.Impact curves,structural deformation and energy dissipation of the door under F4 rank tornado and its windborne debris impact were simulated.Energy dissipation mechanism in impact process was analyzed.Thereafter,a parametric study was performed to investigate the effects of impact locations on the safety performance of the door.The key problems in windborne debris impact resistant design and safety inspection of the door were pointed out.It was shown that the energy dissipation mechanism and the impact curves are influenced by impact locations of windborne debris to a certain extent.

Key words
