Abstract

This paper aims at providing a brief experimental study on the behaviour of uniaxially loaded reinforced concrete slender column with different percentage of longitudinal reinforcement ratio with uniaxial loading. Totally six column specimens were cast with dimensions 2500mm X 200mm X 200mm for testing of uniaxial loaded column with different eccentricity like 200mm and 400mm.For the conduction of the test an unique self-straining loading frame with a range of capacity to apply axial to biaxial loads has been conceived, fabricated and erected indigenously. In this paper, the experimental results are presented, and the global behaviour of tested columns is discussed, particularly focusing on the deflection, stiffness and ultimate loads because of the increasing the eccentricity The results shows by increasing the axial load capacity is reduced, than stiffness is gradually decreasing 1/3 of axial load and ultimate load is decreased from central axial load for eccentricity 200mm and 400mm.
