Modern construction continually evolves with innovations in material technology. A notable advancement in this realm is using fiber reinforced polymers (FRP) to confine concrete, enhancing its strength, ductility, and durability. FRP jacketing and confinement offer a corrosion-resistant, effective, and sustainable solution to the structural rehabilitation of concrete structures. However, the mechanics of FRP confinement are not well understood. The Mechanism of Fibre-reinforced Polymer Confinement in Concrete Structures fills the key knowledge gaps in the field, offering an all-encompassing resource: from the material level to the structural level, including FRP confinement mechanism, governing factors, constitutive behavior, and columns' plastic hinge problems. - Provides a detailed overview of the use of fiber reinforced polymers (FRP) to confine concrete, covering both advantages and disadvantages - Examines true-triaxial behavior, providing insight into lesser-explored yet crucial areas - Includes guidance on dealing with eccentric loads and understanding plastic hinge behavior in reinforced concrete columns
