碩士 === 中正理工學院 === 軍事工程研究所 === 88 === Abstract To study maximum dynamic load and scabbing phenomena of reinforced concrete plates under impact, 3 kinds of simply supported reinforced concrete plates, were tested by a MTS high rate test system using open-loop method. When subjected to a impact with a velocity of 5.65 m/s, the major finding for the reinforced concrete, having the aspect ratio of 1:1、1:1.5 and 1:2, are : The ratio of maximum dynamic load to its corresponding static load for the plates are 8.96、7.76 and 6.43.The rear scabbing volume is 34.35%、22.36% and14.6% of the whole concrete plate volume. ;And which compared with the scabbing volume of 1:1 reinforced concrete plates are 1: 0.98: 0.85.
