摘要：
In order to investigate the tension-stiffening effect of reinforced Engineered Cementitious Composite (ECC), which is one of the High Performance Fiber-Reinforced Cementitious Composite (HPFRCC), uniaxial tension test is carried out for the specimens with one deformed steel rebar arranged. Bond analysis between ECC and rebar, in which fiber bridging effect of ECC at crack is considered, is conducted under the assumption of the bond stress -slippage relationship. Analysis results show that the tension-stiffening effect between ECC and steel rebar is relatively small rather than bridging action of ECC. It is also confirmed that bridging stress is smaller than crack strength of ECC as the average and strain capacity of ECC increases due to restriction of crack localization.
