In this study, experimental study on the missile impact behavior of the nuclear power plant SC(steel plate concrete) wall was carried out to set up the future direction for the reasonable design method development.
Four set of actual impact test of the SC wall were conducted at the EMRTC site located in Socorro, New Mexico. Initial and residual velocity of the missile, strain and acceleration of the back plate, local failure mode and deformation size, etc. were measured to study the local failure behaviour of the specimens. Finally, the experimental results are compared with the local failure evaluation formula and future research direction for the refined design method of the SC wall was reviewed.
