Abstract

In the Japanese Design Code for Concrete Reactor Vessels, design allowable concrete temperatures (normal operation: general area 65 °C, local area 90 °C) are specified. To evaluate the impact response of the reinforced concrete structure under high temperature conditions it is important to investigate the strain rate effect of concrete under such high temperature. Therefore, a series of static and dynamic tests at strain rates from 10"*Vs to lOVs with the concrete test specimen (water-cement ratios of 0.5and 0.6) were studied experimentally using a hydraulic loading system and a Split Hopkinson Pressure Bar (SHPB) type loading system. In the SHPB test sy
