REVIEW OF EFFECTS OF LOADING RATE ON CONCRETE IN COMPRESSION

This paper surveys and summarizes the research in the behavior of concrete subjected to dynamic compressive loading. General conclusions on the effects of strain rate on some mechanical properties of concrete under compression are presented. It was found that both compressive strength and stiffness increase with increasing strain rates, and that increasing of the rate of strain has not resulted in consistent increase or decrease in ultimate strain and strain at maximum stress. Higher strain rates appear to have a more profound effect on low to moderate strength concrete than on high-strength concrete. Wet concrete is relatively more sensitive to a change in loading rate than dry concrete. These and other findings are dicsussed.
