Abstract

Current Tsunami disaster events have indicated that the needs of Tsunami evacuation buildings. Such buildings should be designed to withstand not only wave pressure of Tsunami but also collision of flotsam carried by Tsunami. With respect to the collision of flotsam, the quantitative design method has not been established so far. In this paper, we carried out the impact loading test of concrete-filled steel tubular (CFT) members because CFT members can resist well against locally intensive loads at collision surfaces. For the comparison, vacant steel tubular members are also tested. Being based on the experimental results, we discuss the collapse modes, energy balance between input energy by impact loads and energy absorption capacity of CFT members, and the balance between the impulse and the momentum. In order to make clear dynamic effects in impact loading test, static loading test is conducted as well.
