[9. Description of specific configuration example of elastic-plastic hysteretic damper]
20 (A) and 20 (B) is projected outward from the distal ends of the shearing portions 11 and 11 of the horseshoe-type elastic-plastic hysteresis damper 10 shown in FIG. a flat reinforcing plate is formed as, may be as a reinforcing portion 13 (see FIG. 11 (C)). In the example of FIGS. 21A and 21B, the shearing portions 11 and 11 are formed substantially parallel to the flat plate-like connecting portion 12, and the interval is extended from the base end portion to the distal end portion of the shearing portions 11 and 11. It may be constant. At this time, reinforcing portions 13 and 13 projecting outward may be formed at the front ends of the shearing portions 11 and 11 by welding. Of course, the reinforcing portions 13 and 13 may be formed by bending the tip portions of the shearing portions 11 and 11 instead of welding. Further, in the connecting portion 12, portions that protrude outward from the base end portions of the shearing portions 11 and 11 become reinforcing portions 17 and 17. Note that the angle formed by the reinforcing portions 13 and 13 and the shearing portions 11 and 11 may be not only a right angle but also an acute angle or an obtuse angle. In the example of FIGS. 22A and 22B, the whole is formed in a substantially V shape, the connecting portion 12 that connects the shearing portions 11 and 11 has an acute angle, and the tip of the shearing portions 11 and 11 is outward. Reinforcing portions 13, 13 are formed so as to overhang. Although the reinforcement parts 13 and 13 here may be welding joining, they are formed by the bending process.
図２５（Ａ）及び（Ｂ）の例では、二つの剪断部１１，１１に、剪断部１１，１１とベースプレート１４との接合部及び／又は剪断部１１とプレート１５との接合部となる側縁部を切り欠いた孔部２１が断続して複数形成されている。孔部２１は、ベースプレート１４との接合部及び／又はプレート１５との接合部に形成されることで、ベースプレート１４との接合部及び／又はプレート１５との溶接部分を減らすことが出来る。また、剪断部１１，１１は、複数の孔部２１が形成されることによって、例えば剪断部１１，１１に低降伏点鋼を用いなくても、通常の鋼材で低降伏点鋼のような剪断変形をさせることが出来る。なお、孔部２１の形状は、凹字型、半円型等どの様な形状であっても良い。また、孔部２１の数や大きさは、用途に応じて適宜決定すればよい。また、孔部２１は、剪断部１１，１１の連結部１２及び／又は補強部１３との境界の部分に形成するようにしても良い。 In the example of FIGS. 25A and 25B, the two shearing portions 11, 11 are connected to the shearing portions 11, 11 and the base plate 14 and / or the shearing portion 11 and the plate 15. A plurality of hole portions 21 having a cut-out edge portion are formed intermittently. The hole 21 is formed at the joint with the base plate 14 and / or the joint with the plate 15, thereby reducing the joint with the base plate 14 and / or the welded portion with the plate 15. Further, since the plurality of hole portions 21 are formed in the shearing portions 11 and 11, for example, even if the low yield point steel is not used for the shearing portions 11 and 11, the shearing portions 11 and 11 are made of a normal steel material like a low yield point steel. It can be deformed. The shape of the hole 21 may be any shape such as a concave shape or a semicircular shape. Moreover, what is necessary is just to determine suitably the number and magnitude | size of the hole part 21 according to a use. Further, the hole 21 may be formed at a boundary portion between the shearing portions 11 and 11 and the connecting portion 12 and / or the reinforcing portion 13.
図２７（Ａ）及び（Ｂ）も、図２５及び図２６の変形例であり、剪断部１１，１１とベースプレート１４との接合部及び／又は剪断部１１とプレート１５との接合部の一部となるコーナ部に、孔部２３を形成するようにしている。このような図２７の例によっても、ベースプレート１４との接合部及び／又はプレート１５との溶接部分を減らすことが出来、また、剪断部１１，１１に低降伏点鋼を用いなくても、通常の鋼材で低降伏点鋼のような剪断変形をさせることが出来る。なお、孔部２３を設ける位置は、これら四カ所のうち少なくとも一カ所に設けるようにすれば、特に限定されるものではない。例えば、上二個でも良いし、下二個であっても良いし、前面側二個でも良いし、背面側二個でも良い。また、孔部２３の形状は、扇状に限定されるものではなく、例えば矩形状であっても良い。 FIGS. 27A and 27B are also modifications of FIGS. 25 and 26, and are a part of the joint between the shearing portions 11 and 11 and the base plate 14 and / or the joint between the shearing portion 11 and the plate 15. The hole 23 is formed in the corner portion. 27, the joint portion with the base plate 14 and / or the welded portion with the plate 15 can be reduced, and even if the low yield point steel is not used for the shear portions 11 and 11, it is normal. It is possible to cause shear deformation like low yield point steel. The position where the hole 23 is provided is not particularly limited as long as it is provided in at least one of these four places. For example, the upper two pieces, the lower two pieces, the front side two pieces, or the back side two pieces may be used. Moreover, the shape of the hole part 23 is not limited to a fan shape, For example, a rectangular shape may be sufficient.
