Analytical Study of Confined Reinforced Concrete Members using the Three-Dimensional Nonlinear Finite Element Method

Abstract

The present thesis entitled "Analytical Study of Confined Reinforced Concrete Members using the Three-Dimensional Nonlinear Finite Element Method" includes an analytical study of reinforced concrete bridge piers of solid and hollow section with various transverse reinforcement arrangements. A variety of confinement patterns is examined, such as closed overlapping hoops and transverse links, and effectiveness of confinement is assessed in each of them. A key issue is to suggest the most convenient confinement arrangements in terms of enhanced strength and ductility, as well as ease of construction and cost effectiveness. Modelling of bridge sections is performed using three dimensional solid (brick) elements for concrete and embedded linear truss elements for reinforcement bars. In this context, direct simulation of the confinement effect is achieved, emanating from the induced restriction of concrete expansion due to axial tension of lateral reinforcement bars, under concentric monoton ...
