This paper experimentally studied influences of the types of longitudinal rebars and transverse reinforcement methods on seismic behavior of circular fly ash concrete column. The experimental results have indicated that specimens with high strength rebars having low bond strength exhibit smaller residual deformation and more stable resistance than that of the specimens with high-strength deformed rebars. The specimens confined by steel plates shoved not only shoved higher lateral resistance but also less residual deformation than the specimens confined by conventional spirals.
