Behavior of Concentrically and Eccentrically Loaded Hollow Circular Lightweight Self-Consolidating Concrete Columns Reinforced with Glass- and Basalt-FRP Bars and Spirals

To date, integrating fiber-reinforced polymer (FRP) bars as a valuable option as internal reinforcement for concrete members has gained significant interest in the construction industry, due to their corrosion resistance and high tensile strength-to-weight ratio. The use of hollow reinforced concrete (RC) columns (HCCs) instead of solid columns has increased in the construction of bridges with high elevations and long spans (e.g., bridge piers, bridge columns, and piles). The advantages that HCCs provide over solid columns with the same dimensions relate to enhanced structural efficiency (i.e., higher stiffness-to-weight and strength-to-weight ratios), which can be attributed to the decreased mass contribution of the columns to seismic response and to the lower amounts of concrete materials, thereby reducing costs. The incorporation of FRP reinforcement into hollow lightweight self-consolidating concrete (LWSCC) circular columns would significantly contribute to the production of lighter and more durable reinforced concrete (RC) structures. Large-scale hollow (LWSCC) circular columns will be tested under concentric and eccentric loads.
