FORMULATION OF HYSTERESIS LOOP FOR CONCRETE SUBJECTED TO COMPRESSIVE CYCLIC LOADING

Abstract

Failure of concrete subjected to uniaxial compression is localized, which governs structural behavior of concrete, especially in the post-peak region. In this study, compressive cyclic loading tests were conducted to formulate the hysteresis loop of concrete in compression taken into account the localized failure. As a result, the proposed formulas in this paper can represent the experimental stress-strain curve with good accuracy, which have been obtained from specimens with various height to depth ratio H/D and cross-sections.
