PROBLEM TO BE SOLVED: To provide a compound vibration-control frame with a simple structure reducing responses to external forces of both of an earthquake and the wind by installing viscoelastic dampers in a structural plane formed by columns and beams. SOLUTION: In the compound vibration-control frame, first and second viscoelastic dampers are arranged to have a truncated chevron shape or an inverted truncated chevron shape in the structural plane forming a column-beam frame of a building. An end of each of axis lines of the first and second viscoelastic dampers intersects with an intersection of axis lines of a column and a beam at a column-beam joint part on each of right and left sides of the structural plane. The other end of each of the axis lines of the first and second viscoelastic dampers intersects with the axis line of the beam above or below the column-beam joint part in a manner that an interval is formed between the intersections of the axis lines of the first and second viscoelastic dampers and the axis line of the beam. The interval between the intersections on the beam has a smaller shear yield force than a vertical direction component of a maximum bearing force of the first and second viscoelastic dampers.
