Conventionally, the load-bearing frames that make up the framework of buildings include rigid structures with shear walls or braces as horizontal force resistance elements, and flexible structures with flexible walls, flexible braces, etc. arranged on rigid frames. There is. The majority of wooden houses and other low- and medium-rise buildings are rigid structures. By the way, a rigid structure has a small energy absorption capacity and requires a large amount of human effort during an earthquake.Therefore, the external force for design is also large, and it may not be easy to ensure strength and rigidity.

ある。 This invention was developed to solve the above problems, and basically improves the bending resistance and energy absorption ability of the members that make up the load-bearing frame.
In addition, we aim to obtain the necessary strength and rigidity by changing the material and dimensions of the parts, and to reduce the labor required for processing contacts by making them prefabricated and making use of the ease of connecting parts such as shaft assemblies. It is something to do.

The gist of this invention is that a plurality of annular members for adjusting the rigidity of the frame are arranged in a row within a rectangular frame made of linear members, and the areas where the linear members and the annular members contact each other are connected with pins. This is a load-bearing frame, which reduces in-plane rigidity and improves deformation followability compared to conventional rigid structures. explain.
第１図、第２図においてこの耐力フレームは方
形枠体１と環状部材２からなり、その材質は木
質、鋼あるいは合成樹脂が適宜選択される。
In FIGS. 1 and 2, this load-bearing frame consists of a rectangular frame body 1 and an annular member 2, the material of which is appropriately selected from wood, steel, or synthetic resin.
方形枠体１は水平の各直接部材１ａ，１ｂを接
合プレート３等を使用してピン接合される。また
隅角部には取付金具４を設ける。 In the rectangular frame 1, horizontal direct members 1a and 1b are pin-joined using a joining plate 3 or the like. Also, a mounting bracket 4 is provided at the corner.
環状部材２は複数個一列状に配置して使用さ
れ、方形枠体１によつて囲まれる面内に、かつ方
形枠体を構成する直線部材１ａ，１ｂと環状部材
２および環状部材２同志が接する箇所をボルト５
によつてピン接合される。 A plurality of annular members 2 are used arranged in a line, and within a plane surrounded by the rectangular frame 1, the linear members 1a, 1b, the annular member 2, and the annular members 2 forming the rectangular frame are arranged in a row. Bolt 5 at the contact point
Pin-joined by.
以上の耐力フレームに水平力Ｐが作用すると例
えば曲線部分Ａの両端連結部A1，A2が水平に相
対移動し、曲線部分Ａの曲率が変わる。 When a horizontal force P acts on the above load-bearing frame, for example, the connecting portions A 1 and A 2 at both ends of the curved portion A move relatively horizontally, and the curvature of the curved portion A changes.
すなわち環状部材２は曲げて受けて変形する。
そしてこの変形量は従来のブレース等の場合には
比較して非常に柔らかであり、第３図に示すよう
な挙動の差となり、地震時の入力を減らし、吸収
エネルギーを増大する。 That is, the annular member 2 is bent and deformed.
This amount of deformation is very soft compared to conventional braces, resulting in a difference in behavior as shown in Figure 3, reducing input during an earthquake and increasing absorbed energy.
第４図，は方形枠体１と環状部材２の種々

形の外、楕円形、多角形等に形成することができ
る。 FIG. 4 shows various variations of the rectangular frame 1 and the annular member 2. The annular member 2 can be formed into a shape other than a circle, an ellipse, a polygon, etc.

This invention consists of the above-mentioned structure, and by arranging a plurality of stiffening members arranged in a rectangular frame in a row, the amount of deformation thereof behaves very softly, and the stiffening member is annular. Significant energy absorption. Further, there is no need to pin-join or rigidly connect the contact points of the joint portions of each member, and a finish that does not cause misalignment of each contact point is sufficient, and processing and assembly time can be reduced. Furthermore, the bending rigidity can be controlled by adjusting the thickness of the member in the force direction.
さらに環状部材は方形枠体を構成する直線部材
の座屈止めの作用をもたらす。 Furthermore, the annular member serves to prevent buckling of the straight member constituting the rectangular frame.
