Abstract

PROBLEM TO BE SOLVED: To improve the executability by preventing a corner part of a connection part from a shearing yield part to a mounting part from becoming a right-angled shape when the shearing yield part is joined on a support member in the mounting part. SOLUTION: A corner part 10 of a connection part 9 in which a steel damper 6 moves from a shearing yield part 7 to a mounting part 8 is not right-angled, but is like round shape to prevent weakening due to the concentration of stress at the time of machining and prevent cutting of the corner part 10 only due to the concentration of stress in the corner part 10 when earthquake occurs. Next, the damper 6 is joined on a support member by a high strength bolt through a bolt hole 12 while pressing the mounting part 8 by a pressing plate or the mounting part 8 and the connection part 9 are welded on the support member by fillet welding. Then, when a ratio of width to height of the yield part 7 is large, a rib led to the mounting part 8 is attached to both sides of the yield part 7 by fillet welding to prevent bending deformation which is independent of deformation between layers. Consequently, the deformation between layers due to horizontal force of earthquake can be securely transmitted to the shearing yield part and this steel damper can be manufactured inexpensively because its structure is simple and can be easily mounted because its weight is light.

A steel damper constituting a shear yielding portion will be described with reference to FIGS. FIG. 2A shows the shape of the steel damper when fillet welding is employed as a means for joining the steel damper to the support member. The steel damper 6 is manufactured by forming a D-shape from a steel plate such as ultra-low yield point steel, SS400 or the like, and at the time of shaping, shifts from the central shear yielding portion 7 to the upper and lower mounting portions 8. Special attention has been paid to the joint 9.

The corners 10 at both ends of the connecting portion 9 are formed to have a so-called radius so as to avoid simply connecting the shear yielding portion 7 to the upper and lower mounting portions 8 at right angles. That is, if the connecting portion 9 is formed in a right angle shape, first, shear stress is concentrated at the time of cutting of the mold, and the corner portion 10 is weakened, which is not preferable. However, although it is necessary to absorb the interlayer deformation in the entire shear yielding portion 7, stress is further concentrated on the weakened corner 10 and there is a high possibility that only the corner 10 is cut and collapsed. Because it becomes. Therefore, in order to avoid the above-mentioned double stress concentration, the corner 10 of the joint 9 is formed in a shape having an R, avoiding a right angle.

FIG. 3 (a) shows the shape of the steel damper when fillet welding is employed as a means for joining the steel damper to the support member, which is different from the shear yielding portion 7 in FIG. 2 (a). The shape of the steel material damper 13 when it is made into a shape is shown. At the stage of designing to absorb a predetermined seismic force by the interlayer deformation of the shear yielding type steel damper, the shape of the shear yielding portion 14 may be forced to increase the ratio of the height to the width. In this case, a bending deformation irrelevant to the interlayer deformation occurs in the shear yielding portion. Therefore, ribs 15 reaching the mounting portion 8 are arranged on both sides of the shear yielding portion 14 to reinforce the shear yielding portion, and unnecessary shearing yielding is performed. Prevent out-of-plane behavior. The mounting of the ribs 15 is performed by fillet welding 16,
