Abstract
In this study, in order to investigate the affections of supporting conditions on impact resistant behavior of the RC slabs, falling-weight impact test and static loading test are conducted taking supporting conditions as variable. Here, the slabs with four edges simply supported, two opposite edges simply supported and the other two edges free, and one edge simply supported and resting on opposite two corner points with three edges free are investigated. From this study, following results are obtained: 1) static punching shear capacity of the RC slab may be almost the same in spite of supporting conditions; and 2) impact resistant capacity of the RC slabs may be almost the same in spite of the supporting conditions, even though crack patterns are different depending on the supporting conditions.
