REVERSAL CYCLIC LOADING TEST OF RC COLUMNS LOCATING HOOP REINFORCEMENT INSIDE AXIAL REINFORCEMENT

Abstract

When RC columns receive cyclic loading with large transformation, the bearing capacity of RC columns tends to decline suddenly after flaking cover concrete. The purpose of this study is to prevent sudden decline of the bearing capacity even in large transformation, by locating hoop reinforcement inside axial reinforcement nearby the base of the RC column. We report about the ductility and extent of damage, from the result of reversal cyclic loading test to the column that is reinforced in this way.
