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
