Effect of Macrosynthetic and Hybrid Fibers on the Behavior of Square Concrete Columns Reinforced with GFRP Rebars under Axial Compression

The durability of steel-reinforced concrete (RC) members reduces significantly under aggressive environmental conditions due to the corrosion of steel rebars. The use of fiber-reinforced polymer (FRP) rebars is an attractive alternative for steel rebars in RC members. However, the brittle failure of FRP RC members is a significant concern. The addition of discrete fibers in FRP RC members can improve their postcracking behavior and provide...
