Non Linear Finite Element Analysis on Confined Concrete Columns under Concentric and Eccentric Compression

Arathy Nath P | Indu Susan Raj

Abstract: For a particular load, it is possible to use different diameter for longitudinal bars, which determines the number of bars and hence the arrangement of reinforcement. This paper studies a nonlinear approach of finite element analysis for twelve square reinforced concrete columns under concentric and eccentric compressive loadings. The diameter for longitudinal bars selected for this study includes 10mm, 12mm and 16mm. All the specimens were laterally reinforced with 6mm ties at 50mm spacing. The behaviour of different arrangement of reinforcement for a column for a particular load is analysed using ANSYS 14.5 finite element software and the results were compared. Results indicate that all the models shows a definite change in the load carrying capacity.
