[2115] DYNAMIC RESPONSE ANALYSIS OF RC SLABS WITH VARIOUS SUPPORT CONDITIONS UNDER IMPACT LOADING
キーワード：RC slab, impact loading, dynamic response, elasto-plastic numerical analysis
In this study, 3D elasto-plastic dynamic response analyses were conducted on rectangular reinforced concrete slabs with various support conditions under impact loading. An applicability of an FE model proposed here was investigated comparing with the experimental results. The results obtained from this study were as follows: 1) configurations of the time histories of the impact force, reaction force, and deflection can be better predicted irrespective of the support conditions; and 2) major crack patterns can be approximately simulated for all cases by means of the proposed method.
