文摘
- •
Squat RC shear walls under freeze-thaw cycles are tested under cyclic reversal loading.
- •
Frost cracks, damage process and failure patterns of the specimens are observed.
- •
Effects of frost action on seismic behavior of the specimens are investigated.
- •
Load-carrying capacity and secant stiffness of the specimens decrease due to the frost action.
- •
Contribution of shear deformation to total displacement increases due to the frost action.
