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 method for evaluating damage degree and a system for implementing the same. A polygonal line including a first break point, a second break point, and a maximum response point is determined from a performance curve of each layer of a building. A maximum interlayer deformation angle of each layer is calculated from a maximum interlayer displacement of each layer and its corresponding interlayer height. A safety margin of each layer is calculated from the maximum interlayer deformation angle and a safety limit deformation angle, safety margins are compared, and one polygonal line having the smallest safety margin is selected. A safety limit point is calculated using the polygonal line selected. Damage degree categories are defined using the first break point, the second break point, and the safety limit point. One damage degree category, to which the maximum response point corresponds, is decided out of the damage degree categories.
