Low-Cycle Flexural Fatigue Behavior of Concrete Beam Reinforced with Hybrid FRP-Steel Rebar

Figure 9

Comparison of fatigue test results of RC beam specimens reinforced by the steel rebar (RC-SR) and by the hybrid FRP-steel rebar (RC-HR): (a) fatigue load-deflection curves measured at midspan [25]; (b) fatigue load-tensile strain curves measured in longitudinal reinforcement; (c) fatigue load-concrete compressive strain curves.
