Zusammenfassung:PROBLEM TO BE SOLVED: To provide a vibration control structure for a building, which effectively protects a skeleton of the building from being destroyed due to dynamic load, and positively generates strength against static load. SOLUTION: In the vibration control structure for the building, a brace 4 of a framework 1 has a viscoelastic damper 9 and a frication damper 10 serially arranged thereon. A fixed plate 6 of the viscoelastic damper 9 has a stopper pin 12 arranged thereon, and a movable plate 8 has a slot 13 formed therein, in which the stopper pin 12 is loosely inserted. When vibration occurs, shear deformation of a viscoelastic body 11 of the viscoelastic damper 9 generates a damping action, while at the time of application of excessive load, a fixed plate 7 and the movable plate 8 are relatively moved in a longitudinal direction in the friction damper 10 to generate a friction damping action. On the other hand, with respect to static load such as wind, by virtue of the shear deformation of the viscoelastic body 11, the stopper pin 12 abuts on the slot 13, which brings generation of strength.
