This study presents an experimental investigation into the behavior of lightweight aggregate concrete columns confined with transverse steel reinforcement. Twelve reinforced specimens were tested under monotonically increasing axial compressive load. Test variables considered in the study include the amount of transverse steel and the tie configuration. The results indicated that the crack pattern of confined lightweight aggregate concrete columns exhibited significant differences with the normal weight concrete specimens expressing that the failure planes passed through the coarse aggregates or occurred at the interface between the coarse aggregate and cement paste. In addition, the brittle behavior of lightweight aggregate concrete can be significantly improved by reasonably selecting the tie configuration and adding the amount of lateral steel resulting in an excellent ductile behavior. Columns confined by rectangular hoops with cross ties provide sufficient axial load–carrying capacity and ductile behavior when compared with those of specimens confined by other tie configurations during the test. An analytical model that considers the confinement effectiveness factor (λt) and coefficient k was proposed to predict the peak stress and the corresponding strain of the specimen. The model demonstrates good predictive capability when it is compared with selected models.
