PROBLEM TO BE SOLVED: To provide a vibration control construction of a structure having high workability with a simple constitution and suffering no damage in a main construction of the structure even if an earthquake or the like occurs. SOLUTION: The structure 1 is so constituted that both joint section between a column 2 and a beam 4 by press-contact of PC steel materials 7 and an opening section 9 having a vibration control element 10 are equipped with the vibration control constructions. In case of an earthquake, the earthquake force in the horizontal direction acts on the structure 1 to make relative rotation of the column 2 and the beam 4 by the extension of the PC steel materials 7, and the rigidity of the main construction is lowered. Hence, since the vibration control element 10 maintains horizontal rigidity without changing axial rigidity, earthquake force is largely born, the effect of vibration control is exhibited to control an interlayer deformation of the structure 1, and the relative rotation in the joint section between the column 2 and the beam 4 is made smaller. The joint section between the column 2 and the beam 4 using the PC steel materials 7 having allowable yield proof stress to tinily control the response by the vibration control element 10, and the rotational deformation occurring in the joint section between the column 2 and the beam 4 is completely restored after the earthquake since the PC steel material 7 do not yield.
