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 …

Strengthening of concrete structures with externally bonded carbon fiber reinforced polymers (CFRPs) has been a viable technique for at least a decade and it became interesting material and applied in strengthening reinforced and prestressed concrete beams. It has been found that CFRP sheets are very suitable; not only because of its strength, but also due to its ease of application in comparison to traditional strengthening systems. Despite the fact that CFRP has been widely used in strengthening reinforced concrete members, a very limited works were found in the literature that is related to the application of CFRP in assessing the …
