Abstract

The objectives of this study are to experimentally investigate the effects of loading rate on reinforced concrete shear walls, and to propose material constitutive laws of concrete and rebars accounting for the effects of loading rate. Part 1 of this study shows the results of high speed tensile loading tests of large- size deformed rebars of 38 mm and 51 mm in diameter with the temperature of test specimens varied. The loading speeds were varied from 0.01 cm/s (static) to 200 cm/s. The temperature of the specimens was set to -20°C, 20°C and 60°C, respectively. The regression curves of the yield strength of large-size rebars accounting for effects of bot
