To conduct the integrity assessment on nuclear building subjected to projectile impact, we participated in the third phase of the IRIS project (Improving robustness assessment of structures impacted by a large missile at medium velocity) launched by OECD/NEA. IRIS Phase 3 project contributes to the investigation on the transmission of induced vibrations by projectile impact across the connected floors and walls of the prescribed reinforced concrete (RC) structure with internal equipment. The impact tests of IRIS Phase 3 project were carried out at the VTT Technical Research Center, Finland. On the basis of the test data, we developed and validated an analytical approach to investigate impact response of the RC structure with internal equipment. This paper presents partial analytical results related to the response of RC structure with internal equipment subjected to projectile impact.
