The experimental study was conducted to investigate the shear performance of concrete squat shear walls reinforced with Carbon fiber reinforced polymer (CFRP) rebars. Three concrete shear walls with aspect ratio of 1.0 were constructed and tested up to failure under cyclic lateral loading. Reference specimen (SSW) was a concrete shear wall reinforced horizontally and longitudinally with conventional steel reinforcements. Two specimens (CSW and CCW) with CFRP rebars as longitudinal reinforcement were reinforced with conventional steel and CFRP rebars as horizontal reinforcement, respectively. In test, the effect of reinforcement type on the crack width, load-displacement response and reinforcing bar's strain response of concrete walls was measured and compared.
