Abstract: It is generally accepted that the postpeak strain-softening behavior of concrete in compression is a localized phenomenon that occurs mainly in the compression damage zone. Accurate quantification of the size and slenderness ...

Abstract: The use of fiber-reinforced polymers (FRP) has become widely accepted engineering practice for strengthening reinforced concrete members. It is well established that lateral confinement of concrete with FRP composites can ...

Abstract: It is often assumed that, at a given lateral strain, the axial compressive stress and strain of fiber reinforced polymer (FRP)–confined concrete are the same as those of the same concrete when it is actively confined under ...

Abstract: It is well understood that confining concrete with fiber-reinforced polymer (FRP) composites can significantly enhance its strength and deformability. However, the confinement demand of concrete increases proportionally ...

Abstract: Accurate modeling of the complete stress-strain relationship of confined and unconfined concrete is of vital importance in predicting the overall flexural behavior of reinforced concrete structures. The analysis-oriented ...

Abstract: It is generally accepted that the postpeak strain-softening behavior of concrete in compression is a localized phenomenon that occurs mainly in the compression damage zone. Accurate quantification of the size and slenderness ...

Abstract: A concrete strength-sensitive finite element (FE) model applicable to concrete subjected to various confining pressure levels and conditions is presented. This paper focuses primarily on the failure surface and flow rule ...
