Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vibration control structure for a building frame which facilitates the arrangement of a damper balanced through a simple inexpensive structure and can sharply improve the vibration control ability of the damper. SOLUTION: A column side bracket 22 and a beam side bracket 24 are protrusively provided opposite to each other along an imaginary opposide side L of a triangle having a column 12 and a beam 14 as each one side from a steel frame column 12 and a steel frame beam 14 near a connection point 20 between the column and the beam inside a space partitioned by the column 12 and the beam 14. A friction damper 32 is composed of a pair of slide plates 26, 26 between the column side bracket 22 and the beam side bracket 24; a friction plates 28 which is slidably inserted and overlapped between the slide plates 26, 26; and energizing means 30 for pressing the friction plate 28 between the slide plates 26, 26 in a sandwiching direction. The energizing means 30 is composed using a disc spring where a set pressure contact force is acted to be deflectedly deformed within nonlinear spring domain small in the variation of an elastic repulsive power.
