DETERMINATION OF ELASTICITY MODULUS OF AXIALLY LOADED COLUMNS DEPENDING ON REINFORCEMENT RATIO

Barış ÖZKUL¹

According to the current standards, Elasticity Modulus (Young’s modulus) of concrete and steel materials is given individually. There is no established elasticity modulus exists for reinforced concrete sections. For the displacement calculations, the elasticity modulus is used which is calculated by considering only the compressive strength of concrete. However, the section contains steel reinforcements too. In this study, the elasticity modulus of a reinforced concrete section is tried to be determined depending on the reinforcement ratio. A 100 tons capacity axial compression test setup is constructed at the BAU, Engineering and Architecture Faculty, Civil Engineering Department, Structural Laboratory and the prepared column specimens are fractured by axial loading. It has been seen from experimental results that the elasticity modulus increased by increasing reinforcement ratio of section.
