accurate simulations of seismic behavior of 2 coupled wall specimens and 2 cantilever structure wall specimens using high performance fiber reinforced concrete (FRC) in plastic hinge under quasi static cyclic loading were carried out. The analysis model proves to be effective with the accordance between results of computation and experiment

then it can be used to analyze the seismic behavior of coupled wall system with FRC coupling beams. By using the verified numerical model

the ability of FRC coupling beams instead of RC coupling beams to provide acceptable performance was discussed. In addition

the impact of coupling ratio on seismic behavior of coupled walls was studied. The results show that coupled walls in which FRC coupling beams are used instead of traditional RC beams have good energy dissipation and ductility

and its initial stiffness is increased and stiffness degradation is slow. And as the coupling ratio of coupled wall structures increases

the stiffness and strength increase. But if the coupling ratio is too large

the ductility and energy dissipation capacity will be significantly reduced.
