PURPOSE: To introduce prestress and to perform damping of bending vibration by a method wherein a joint part or an auxiliary member formed of a superresilient alloy material is arranged in the middle of or in parallel to tensile materials arranged in layers to a bending-deformed column.

CONSTITUTION: Fixing members 4 and 5 are arranged at an upper layer 2 and a lower layer 3 at columns at two ends where there is the possibility for a multilayer building 1 to effect bending deformation. Tensile materials 6, 6 serving as a prestress material are arranged in layers from the upper layer 2 to the lower layer 3. In this case, a joint part 7 formed of an superresilient alloy is arranged at the intermediate part of the tensile material 6 to introduce prestress. Further, an auxiliary member of a superresilient alloy is arranged in parallel to the tensile material 6 to introduce prestress. The tensile materials 6 are arranged to both columns, to which bending deformation occurs, of a compression column and a tensile column and the tensile forces are fluctuated in a reverse direction to each other along with the fluctuation of the axis of the column. In this case, the superresilient alloy material absorbs energy of the fluctuation tensile force of the tensile material 6.
