| dc.description.abstract | Ductility is the ability of a structure or its components to offer resistance in the inelastic domain of response. However, concrete is not a ductile material, and therefore, confinement is recommended to improve its performance. Confinement in concrete is achieved by the suitable placement of transverse reinforcement, which results in a significant increase in the strength and ductility of concrete. This paper focuses on the confinement effect induced by different arrangements of transverse reinforcement on axially loaded concrete columns. The aim of this research is to carry out a parametric study on the confinement action induced by a type of stirrup involving steel plates and different arrangements of transverse reinforcement on axially loaded concrete columns. To achieve this goal, numerical analysis was conducted using the finite element program, ABAQUS. The variables considered in this study were concrete compressive strength, spacing of transverse reinforcement, arrangement of transverse reinforcement, and influence of plate thickness. The results of numerical studies have shown that the effect of concrete compressive strength and longitudinal reinforcement ratio have the most impact on the column response, the spacing of transverse reinforcement has less impact and the effect of plate thickness almost negligible. Additionally, the configuration of transverse reinforcement involving steel plates has been found to improve a column's strength and its ability to withstand axial loads. | |
