The utility model belongs to the field of recoverable functional structure systems, and relates to a replaceable shear wall foot support based on shape memory alloy, which comprises a tension and compression combined shock absorption and isolation part and a shape memory alloy wire. The shape memory alloy wires are spirally fixed to an upper connecting steel plate and a lower connecting steel plate of the tension-compression combined shock absorption and isolation component through positioning blocks, the upper connecting steel plate is connected with the shear wall through bolts, the lower connecting steel plate is connected with a lower floor component through bolts, and the novel replaceable shear wall foot support is formed. The method is simple in construction, the hyperelasticity anddeformation restorability of the shape memory alloy material are fully utilized to be applied to the shear wall foot with the restorable function, and the method has the multiple advantages that earthquake energy dissipation
