Outline of Final Research Achievements

In order to design tsunami-resistant RC buildings, development of design methods for debris impact loads is necessary. In this study, impact tests were conducted using a lateral impact loading system to evaluate the performance of RC buildings. Thirty-six RC wall specimens were tested to investigate the effects of impact load on local damage. Damage of specimens was classified as penetration, scabbing, and perforation. The limit impact velocity for scabbing and perforation was evaluated by proposed equations which was modified from Hughes' equations. The proposed equations evaluated the limit impact velocity for scabbing and perforation with good accuracy.
