Abstract: A fracture caused by fatigue of a connecting portion positioned at a corner of a reinforcing frame directly secured to a frame is avoided regardless of a relative displacement that occurs in the frame upon disposing the reinforcing frame made of steel, which has an elevational shape surrounding the frame along an inner circumferential surface of the frame and a cross-sectional shape with a flange on a side of the frame, in a structure plane of the frame of a column and a beam of reinforced concrete structure, and joining the reinforcing frame to the inner circumferential surface of the frame. A reinforcing frame is constituted of a column portion along a column of a frame, a beam portion along a beam, and a connecting portion that is joined to the column portion and the beam portion, and connects the column portion to the beam portion.

Abstract: In between a shear wall of a reinforced concrete structure disposed in a column and beam frame of a reinforced concrete structure and the frame, transmission capability of a shear force between is enhanced from a stage which a relative deformation occurs among between the frame and the shear wall. Plate is disposed between an inner peripheral surface of a frame and an outer peripheral surface of a shear wall, integrated with any one of the frame and the shear wall, and continuous in a longitudinal direction and in a height direction of the shear wall and penetrate the plate in a thickness direction. The anchors are dispersedly in the longitudinal direction and in the height direction of the shear wall.

Abstract: A damping device for structure includes a base frame installed on a target place, an air floating mass disposed on the base frame to blow off air, a TMD mass disposed above the base frame to float with an air pressure, one pair of guiderail units disposed on X-direction both sides of the base frame along the X direction respectively, slider units disposed to be slidable in the X direction relative to the guiderail units, coupled to each X-direction side face of the TMD mass and each including a slider moving up/down mechanism part which moves down a slider when the TMD mass floats, an oil damper attached to the base frame to exert an attenuation action on the TMD mass and a coil spring attached to the base frame to exert a restoration action on the TMD mass.
