It is proved that fiber orientation significantly affects the confinement of fiber-reinforced polymer (FRP) wrapped concrete members. The inclination of fiber relative to the hoop direction reduces confinement effectivity. In addition, most available

In order to achieve active confinement in concrete elements, researchers have recently employed smart materials called shape memory alloys (SMA). Several empirical relationships have been widely used to predict the behavior of confined concrete. To d

In this paper, a new series of applicable relations, including maximum confined stress and strain as well as the stress–strain relationship, for AFRP confined concrete are proposed based on the design-oriented approach. The main advantages of these
