PURPOSE:To enhance the rigidity of a building in its entirety by arranging a viscoelastic member between the inner surface of a steel plate with which the opposite side surfaces and the lower end surface of an end part of a beam are covered, between a column and the beam so that the viscoelastic member is fixed at one end to the column and at the other end to the beam. CONSTITUTION:At a joint between a steel pipe concrete column 4 and a precast steelwork concrete beam 2, a low-yield steel joint member are rigidly fixed at its opposite ends to the column 4 and the beam 2. Further, a steel plate 7 with which the opposite side surfaces and the lower end surface of an end part of the beams 2 are covered, is joined at opposite ends to the column 4 and the beam 2 through viscoelastic members. A damping unit using viscoelastic members is fixed at its opposite ends to the column 4 and the beam 2 by welding or the like. With this arrangement, the structural continuity between the column 4 and the beam 3 can be enhanced, and vibration of a building, caused by an earthquake or the wind, can be absorbed and damped by the joint members at the joint between the beam and the column.
