Abstract

Replacement of steel in reinforced concrete (RC) walls with corrosion-resistant rebars became essential to improve durability of RC structures. Hybrid usage of stainless-steel (SS) and glass fiber reinforced polymer (GFRP) is proposed. SS rebars are utilized as concentrated reinforcement (RFT) in plastic hinge regions while GFRP rebars are used elsewhere. This combination of rebars has the advantage of providing adequate ductility and strength needed to resist both gravity and lateral forces effectively. A comprehensive parametric study is conducted on a large number of RC walls with different dimensions and RFT ratios. Pushover analysis is utilized to analyze the RC walls using a robust finite element software. The results of the parametric study are utilized to develop a set of design equations that can be used to estimate amount of SS-GFRP RFT as a replacement to steel rebars.The obtained corrosion-resistant walls have stiffness, lateral strength, and ductility equivalent to the steel reinforced walls.The developed equations are examined by investigating the response of a case study RC building under seismic loading
