Nonlinear Concrete Behaviour, Marian Sabau, Traian Onet Nov 2011

Nonlinear Concrete Behaviour, Marian Sabau, Traian Onet

Marian Sabau

This paper presents an overview of nonlinear behaviour in reinforced concrete structures. Structural concrete is a nonlinear material both at strength limit states and service loads. Are presented terms of effects that are primarily observed in concrete, steel or a combination of the two. When considering nonlinear behaviour, an important aspect is whether or not strain localization will occur as size effects. The model must first be validated by experiments and benchmark tests to ensure the safety and reliability criteria. In nonlinear finite element procedures, engineers must check their finite element discretization and modelling assumptions used in their analyses. Advanced …
