Modeling of shear‐critical reinforced engineered cementitious composites members under reversed cyclic loading
Engineered cementitious composites (ECC) possesses characteristics that make it suitable in the zones of high ductility and high‐shear demand of structural elements. In this study, a numerical modeling method for simulating shear‐critical reinforced ECC members was put forward. Uniaxial cyclic constitutive models of ECC in compression and tension were proposed, including unloading and reloading scheme. Softening phenomenon and Poisson effect of cracked ECC were also considered in the proposed 2‐dimension constitutive model. The proposed model was coded into the simulation of concrete structures program in the OpenSEES platform to simulate the structural responses. Four short RECC and ECC/RC columns were tested under reversed cyclic lateral loading and constant axial loading, to verify the proposed model. In addition, the recorded hysteretic responses of RECC and ECC/RC shear walls subjected to reversed cyclic loading were compared with the simulated hysteretic loops. Results of comparative analysis indicate that the proposed model is reasonably accurate in simulating the mechanical properties of shear‐critical reinforced ECC members.
