Four RC shear wall specimens with a shear span ratio of 1.14 were subjected to rapid action of freeze-thaw cycles in artificial climate room，and then the quasi-static tests were carried out to study the deterioration of seismic behaviors of the shear walls under different action of freeze-thaw cycle.Six performance indicators，such as load carrying capacity，ductility，plastic rotation，strength degradation，stiffness degradation，and cumulative hysteretic energy dissipation，were used to evaluate the influence of the number of freeze-thaw cycles on the seismic behaviors of squat RC shear wall.The Results reveal that the embedded column and distributed reinforcement could restrain the growth and widening of frost heaving cracks and slow down the damage caused by freeze-thaw.With the increase of the number of freeze-thaw cycles，shear deformation is becoming more obvious in total deformation and the failure mechanism is changing from apparent flexure-shear dominated by flexural deformation to flexure-shear dominated by shear deformation gradually.The deterioration laws of seismic behaviors of the shear walls under action of freeze-thaw cycle are as fallows：with the increasing of the number of freeze-thaw cycles，the shear capacity is significantly reduced，but there is a significant increase in the ductility and plastic rotation; the degradation rate of strength is accelerated，and energy dissipation capacity is steadily deteriorated.
