The invention discloses an SMA-friction pendulum clearance compound isolation bearing. The isolation bearing comprises an upper bearing plate, a cylindrical double-protruding-spherical-surface sliding block and a lower bearing plate. An SMA wire super-elastic component is arranged between the outer wall of the lower portion of the upper bearing plate and the outer wall of the upper portion of the lower bearing plate. The central concave surface of the upper bearing plate is connected with the upper protruding spherical surface of the cylindrical double-protruding-spherical-surface sliding block, and the lower protruding spherical surface of the cylindrical double-protruding-spherical-surface sliding block is seated in the concave surface of the lower bearing plate. The isolation bearing has the advantages of being simple in structure, high in bearing force, good in durability, adaptive in isolation performance and the like and is applicable to buildings, bridges, aqueducts and other structures in meizoseismal areas.
