Özet

Fiber Reinforced Polymers (FRPs) are widely recognized for their advantages including

low weight, high tensile strength, and resistance to corrosion. This study aims to

investigate the structural behavior of Autoclaved Aerated Concrete (AAC) beams that

are strengthened with externally bonded FRP laminates. An experimental program was

carried out using unidirectional carbon fiber laminates placed in single layers, either

partially (half-width) or fully covering top and bottom faces of the beams. The

experimental results were analyzed in terms of stiffness, ultimate strength, and ductility.

In addition to experimental work, a numerical study was performed using both section

analysis and nonlinear finite element modeling (FEM) to predict the load-deformation

behavior of the specimens. The effective FRP strain values obtained from the analyses

were also compared with the provisions of ACI 440.2R. Findings indicate that a

reduction factor of approximately 60% should
