Description

本発明は、木質ラーメン構造における柱梁接合部の剛性を評価する評価システムに関する。   The present invention relates to an evaluation system for evaluating the rigidity of a beam-column joint in a wooden frame structure.

従来から、木造建築物において柱と梁とを剛接合とするために、柱の下端の切り欠きにねじ込まれた２本のスクリュー部材と、この柱にねじ込まれたスクリュー部材と対向する位置の梁にねじ込まれた２本のスクリュー部材とを連結する連結部材によって構成される木質ラーメン構造における柱梁接合構造が知られている（例えば、特許文献１参照）。
この柱梁接合構造は、柱と梁の接合面が強く圧接されるため、高い剛性を有した構造物を得ることが可能となり、柱の位置の自由度が増すため、住宅の間取りの自由度を向上させることができるという特徴を有している。
特開２００４−３０８３４８号公報 Conventionally, in order to rigidly connect a column and a beam in a wooden building, two screw members screwed into a notch at the lower end of the column and a beam at a position facing the screw member screwed into the column There is known a column beam connection structure in a wood ramen structure constituted by a connecting member that connects two screw members screwed into the frame (for example, see Patent Document 1).
In this column-beam connection structure, the joint surface between the column and the beam is pressed strongly, making it possible to obtain a structure with high rigidity and increasing the degree of freedom in the position of the columns. It has the characteristic that can be improved.
JP 2004-308348 A

ところで、木質ラーメン構造における柱梁接合部は、完全な剛接合ではなく、半剛接合として扱わなければならないため、木質ラーメン構造の構造物は、柱梁接合部の実験値を用いて設計を行う必要がある。
しかしながら、特許文献１に示す柱梁接合構造の構造物は、柱の位置の自由度が増すという特徴を有している反面、任意の間取りの構造物を設計する場合は、新たな構造物毎に実験を行わなければならず、多大な手間がかかるという問題がある。 By the way, the beam-to-column joint in the wooden frame structure must be treated as a semi-rigid connection, not a complete rigid connection. Therefore, the structure of the wooden frame structure is designed using experimental values of the beam-column connection. There is a need.
However, the structure of the beam-column joint structure shown in Patent Document 1 has a feature that the degree of freedom of the position of the columns is increased. However, when designing a structure with an arbitrary floor plan, every new structure is provided. There is a problem that it takes a lot of time and effort to conduct experiments.

このような問題を解決するためには、想定される構造物に加わる外力の最大値に耐える剛性を有した柱梁接合部とすればよいが、剛性を高めるために、複雑な接合方法を用いると、組み立て時間が長くなったり、柱梁接合部の部材のコストが増大するなどの問題がある。また、柱梁接合部の位置に応じて、接合部の部材や接合方法を変えるのは、組み立ての作業性が悪くなるとともに、柱梁接合部の部材のコストが増大してしまうという問題があるため、柱梁接合部を構成する部材を最適化する必要がある。   In order to solve such a problem, it is sufficient to use a column beam joint having rigidity capable of withstanding the maximum value of the external force applied to the assumed structure, but in order to increase the rigidity, a complicated joining method is used. As a result, there are problems such as an increase in assembly time and an increase in the cost of members of the beam-column joint. In addition, changing the member and joining method of the joint according to the position of the beam-column joint has problems that the workability of the assembly deteriorates and the cost of the member of the beam-column joint increases. Therefore, it is necessary to optimize the members constituting the column beam joint.

本発明は、このような事情に鑑みてなされたもので、木質ラーメン構造の構造物内に用いられる柱梁接合部の耐力を評価する評価システム及び評価プログラムを提供することを目的とする。   This invention is made | formed in view of such a situation, and it aims at providing the evaluation system and evaluation program which evaluate the proof stress of the beam-column joint part used in the structure of a wooden frame structure.

本発明は、木質ラーメン構造を用いた構造物における柱梁接合部の剛性を評価する評価システムであって、前記柱梁接合部を構成する各部材それぞれをバネ要素として定義し、前記柱梁接合部のモデル化を行うモデル化手段と、前記柱梁接合部のバネ要素モデルに基づいて前記構造物を定義する構造物定義手段と、定義した前記構造物に対して、外力を与えた場合の前記バネ要素の節点変位を計算して出力する計算手段とを備えたことを特徴とする。   The present invention is an evaluation system for evaluating the rigidity of a beam-column joint in a structure using a wooden frame structure, wherein each member constituting the beam-column joint is defined as a spring element, and the beam-column joint is defined. Modeling means for modeling a portion, structure defining means for defining the structure based on a spring element model of the beam-column joint, and an external force applied to the defined structure And calculating means for calculating and outputting a nodal displacement of the spring element.

本発明は、木質ラーメン構造を用いた構造物における柱梁接合部の剛性を評価する評価プログラムであって、前記柱梁接合部を構成する各部材それぞれをバネ要素として定義し、前記柱梁接合部のモデル化を行うモデル化処理と、前記柱梁接合部のバネ要素モデルに基づいて前記構造物を定義する構造物定義処理と、定義した前記構造物に対して、外力を与えた場合の前記バネ要素の節点変位を計算して出力する計算処理とをコンピュータに行わせることを特徴とする。   The present invention is an evaluation program for evaluating the rigidity of a beam-column joint in a structure using a wooden frame structure, wherein each member constituting the beam-column joint is defined as a spring element, and the beam-column joint is defined. A modeling process for modeling a part, a structure defining process for defining the structure based on a spring element model of the beam-column joint, and an external force applied to the defined structure The computer is caused to perform a calculation process for calculating and outputting a nodal displacement of the spring element.

本発明によれば、柱梁接合部を構成する部材のそれぞれに対して、１対１に対応するようにバネ要素を定義し、計算により柱梁接合部の耐力を評価するようにし、柱梁接合部を構成する部材それぞれの影響を把握することができるため、柱梁接合部を構成する部材の改良検討を容易に行うことが可能になり、各部材の最適化を図ることができるという効果が得られる。   According to the present invention, the spring elements are defined so as to correspond one-to-one with respect to each member constituting the beam-column joint, and the strength of the beam-column joint is evaluated by calculation. Since it is possible to grasp the influence of each member constituting the joint, it becomes possible to easily consider improvement of the member constituting the beam-column joint, and to optimize each member. Is obtained.

以下、本発明の一実施形態による評価システムを図面を参照して説明する。初めに、図４、５を参照して、評価する対象である木質ラーメン構造の構造物の概略と柱梁接合部を構成する部材について説明する。図４は、木質ラーメン構造の木造建築物の構造躯体を示す概略斜視図である。この構造躯体は、１階を構成する下層部分及び２階を構成する上層部分が、それぞれラーメン架構体を複数組み合わせて形成されており、これらを積層することによって全体の構造躯体が形成されている。それぞれのラーメン架構体は、木製の柱１、３の上に木製の梁２、４を載置して接合するいわゆる梁勝ち構造となっており、それぞれのラーメン架構体を構成する柱１、３及び梁２、４は、これらの軸線を含む立面と平行な方向の断面寸法を大きく、これと直角方向の断面寸法を小さくして扁平な部材となっている。したがって、各ラーメン架構体の接合部は一方向の曲げに抵抗する構造となっている。   Hereinafter, an evaluation system according to an embodiment of the present invention will be described with reference to the drawings. First, with reference to FIGS. 4 and 5, an outline of a wooden ramen structure structure to be evaluated and members constituting the beam-column joint will be described. FIG. 4 is a schematic perspective view showing a structural frame of a wooden building having a wooden ramen structure. In this structural housing, the lower layer portion constituting the first floor and the upper layer portion constituting the second floor are each formed by combining a plurality of ramen frame structures, and the entire structural housing is formed by laminating them. . Each ramen frame has a so-called beam-winning structure in which wooden beams 2 and 4 are placed on and joined to the wooden columns 1 and 3, and the columns 1 and 3 constituting each ramen frame are formed. The beams 2 and 4 are flat members having a large cross-sectional dimension in a direction parallel to the vertical plane including these axes and a small cross-sectional dimension in a direction perpendicular to the vertical plane. Therefore, the joint portion of each frame structure has a structure that resists bending in one direction.

これらのラーメン架構体は、平面上で方向が互いに直角となるように、すなわち複数のラーメン架構体の梁２−１、２−２、４−１、４−２が互いに直角となるように接合されている。これにより、異なる方向の水平力に抵抗する複数のラーメン架構体が互いに組み合わされ、あらゆる方向の水平力に抵抗可能な構造躯体となっている。そして、上層部分の柱３は、下層のラーメン架構体の梁２上に立設されている。   These frames are joined so that the directions are perpendicular to each other on a plane, that is, the beams 2-1, 2-2, 4-1, and 4-2 of the plurality of frames are perpendicular to each other. Has been. Thus, a plurality of rigid frame structures that resist horizontal forces in different directions are combined with each other to form a structural frame that can resist horizontal forces in all directions. The upper layer column 3 is erected on the beam 2 of the lower frame frame.

図５は、図４に示すラーメン架構体で用いられる下層部分の梁２と上層部分の柱３との接合構造の詳細を示す分解斜視図である。ラーメン架構体を形成する木製梁２と木製柱３との接合構造において、柱３の下端における長辺方向の両端部に切り欠き３ｂを設け、この切り欠き３ｂから柱３の軸線方向に２本のスクリュー部材１１をねじ込む。この柱３にねじ込まれたスクリュー部材１１と対向する位置の梁２に２本のスクリュー部材１２がねじ込まれる。切り欠き３ｂ内にはそれぞれ接合金具３１を介挿し、柱３にねじ込まれたスクリュー部材１１と梁２にねじ込まれたスクリュー部材１２との双方にボルト４１で結合する。接合金具３１は、側部に開口を有するもので、開口の背面側は鉛直方向の円筒曲面を有している。これにより、ボルト４１を中心に切り欠き３ｂ内で接合金具３１が回動が可能となり、ボルト４１の締め付け時において開口部を作業が容易な方向に向けることができる。   FIG. 5 is an exploded perspective view showing the details of the joint structure between the lower-layer beam 2 and the upper-layer column 3 used in the rigid frame structure shown in FIG. In the joint structure of the wooden beam 2 and the wooden column 3 forming the frame structure, the notch 3b is provided at both ends in the long side direction at the lower end of the column 3, and two in the axial direction of the column 3 from the notch 3b. The screw member 11 is screwed. Two screw members 12 are screwed into the beam 2 at a position facing the screw member 11 screwed into the column 3. Each of the cutouts 3 b is inserted with a joint fitting 31, and is connected to both the screw member 11 screwed into the column 3 and the screw member 12 screwed into the beam 2 with a bolt 41. The joining metal fitting 31 has an opening on the side, and the back side of the opening has a cylindrical cylindrical surface in the vertical direction. Thereby, the joining metal fitting 31 can be rotated in the notch 3b around the bolt 41, and the opening can be directed in a direction in which the work can be easily performed when the bolt 41 is tightened.

このような部材を用いて柱梁接合部を構成することにより、組み立てを迅速に行うことが可能であるとともに、柱３と梁２の接合面が強く圧接されるため、高い剛性を有した柱梁接合部を実現することが可能となる。   By constructing the beam-column joint using such a member, it is possible to assemble quickly, and since the joint surface between the column 3 and the beam 2 is strongly pressed, a column having high rigidity A beam joint can be realized.

次に、評価システムの構成を説明する。図１は同実施形態の構成を示すブロック図である。この図において、符号５１は、キーボードやマウス等から構成する入力部であり、使用者が入力操作を行うことにより、構造物の定義や計算条件の入力を行う。符号５２は、前述した柱梁接合部を使用した木質ラーメン構造の構造物を定義する構造物定義部であり、例えば、図４に示す構造物を定義する。符号５３は、柱と梁との接合部をバネ要素でモデル化する接合部モデル化部である。符号５４は、柱と梁との接合タイプ毎にバネ要素の特性（バネ定数）が予め定義されたバネ要素データベースである。符号５５は、構造物定義部５２において接合部モデルの組み合わせにより定義された構造物のデータと入力部２から入力された計算条件に基づいて、各バネ要素の節点変位を計算して出力する計算部である。符号５６は、計算部５５から出力される各バネ要素の節点変位の値を表示する表示部である。   Next, the configuration of the evaluation system will be described.

ここで、図２、３を参照して、バネ要素を用いた柱梁接合部のモデルについて説明する。図２は、柱梁接合部をバネ要素によりモデル化した例を示す図である。図２において、バネ要素ＫＣＳは、柱にねじ込まれるスクリュー部材の軸方向バネであり、バネ要素ＫＢＳは、梁にねじ込まれるスクリュー部材の軸方向バネである。また、バネ要素ＫＦＬは、基礎接合要素の軸方向バネであり、バネ要素ＫＣＬは、接合金具の軸方向バネである。図２に示すように、柱梁接合部を構成する部材のそれぞれに対して、１対１に対応するようにバネ要素を定義し、柱梁接合部のモデル化を行う。図２に示すような柱梁接合部モデルを用いた簡易な骨組構造物を定義し、この構造物に水平力Ｐを作用させた場合の層間変形δは、力の釣合い条件より、次式によって求めることができる。 Here, with reference to FIGS. 2 and 3, a model of a column beam joint using a spring element will be described. FIG. 2 is a diagram illustrating an example in which a column beam joint is modeled by a spring element. 2, the spring element K CS is an axial spring of the screw member to be screwed into the pillar, the spring element K BS is an axial spring of the screw member to be screwed to the beam. Further, the spring element KFL is an axial spring of the basic joint element, and the spring element KCL is an axial spring of the joint fitting. As shown in FIG. 2, the spring elements are defined so as to correspond one-to-one with respect to each of the members constituting the beam-column joint, and the beam-column joint is modeled.

次に、任意形状の骨組構造物については、一般的によく知られている「マトリクス法」を用いて対象構造物の応力と変形を算定する。構造物全体を対象とした座標系を基準座標系とし、構造物を構成する部材（バネ要素を含む）を対象とした座標系を部材座標系とした時、構造物の節点荷重Ｐと節点変位Ｄは以下のように定式化される。なお、ここでは平面骨組構造物を対象とするが、立体骨組構造物に拡張することは可能である。   Next, for an arbitrarily-shaped frame structure, the stress and deformation of the target structure are calculated using a generally well-known “matrix method”. When the coordinate system for the entire structure is the reference coordinate system, and the coordinate system for the members (including spring elements) constituting the structure is the member coordinate system, the nodal load P and the nodal displacement of the structure D is formulated as follows. In addition, although a planar frame structure is targeted here, it can be expanded to a three-dimensional frame structure.

次に、図１を参照して、図１に示す評価システムの処理動作を説明する。まず、評価システムを使用する者（以下、使用者という）は、入力部５１から、例えば図４に示す構造物を定義するデータ（柱の寸法及び位置、梁の寸法及び位置等）を入力する。この構造物を定義するデータの入力は、建築用のＣＡＤシステム等を用いて定義したデータを用いてもよい。このデータ入力を受けて、構造物定義部５２は、入力された構造物データを内部に保持する。そして、使用者は、入力部５１から各柱と梁の接合部に対して、接合タイプを選択する。これを受けて、接合部モデル化部５３は、選択された接合タイプに応じたバネ要素の特性をバネ要素データベース５４から読み出し、各柱梁接合部毎に図２、３に示すモデルを定義して、構造物定義部５２へ受け渡す。   Next, the processing operation of the evaluation system shown in FIG. 1 will be described with reference to FIG. First, a person who uses the evaluation system (hereinafter referred to as a user) inputs data defining the structure shown in FIG. 4 (column dimensions and positions, beam dimensions and positions, etc.) from the input unit 51. . The data defining the structure may be input using data defined using an architectural CAD system or the like. Upon receiving this data input, the structure definition unit 52 holds the input structure data therein. Then, the user selects a joint type for the joint between each column and the beam from the input unit 51. In response to this, the joint modeling unit 53 reads the characteristics of the spring elements corresponding to the selected joint type from the spring element database 54 and defines the models shown in FIGS. 2 and 3 for each column beam joint. To the structure definition unit 52.

次に、構造物定義部５２は、内部に保持している構造物データと柱梁接合部毎のモデルデータ（モデルの種類とバネ特性）を計算部５５へ出力する。そして、使用者は、入力部５１から水平力（外力）の値を入力するとともに、計算開始を指示する。これを受けて、計算部５５は、構造物データと柱梁接合部毎のモデルデータと水平力の値とから各バネ要素の節点変位を計算して表示部５６へ出力する。これにより、表示部５６には、各バネ要素の節点変位の値が表示されることになる。   Next, the structure definition unit 52 outputs the structure data held therein and the model data (model type and spring characteristics) for each column-beam joint to the calculation unit 55. Then, the user inputs the value of the horizontal force (external force) from the input unit 51 and instructs the start of calculation. In response to this, the calculation unit 55 calculates the nodal displacement of each spring element from the structure data, the model data for each beam-column joint, and the value of the horizontal force, and outputs it to the display unit 56. Thereby, the value of the nodal displacement of each spring element is displayed on the display unit 56.

このように、柱梁接合部を構成する部材（柱側のスクリュー部材、梁側のスクリュー部材及びこれらのスクリュー部材を接合する接合金具）のそれぞれに対して、１対１に対応するようにバネ要素を定義し、計算により柱梁接合部の耐力を評価するようにし、柱梁接合部を構成する部材それぞれの影響を把握することができるため、柱梁接合部を構成する部材の改良検討を容易に行うことが可能になり、各部材の最適化を図ることができる。   As described above, the springs correspond to each of the members (column-side screw members, beam-side screw members, and joining fittings for joining these screw members) constituting the column-beam joint portion in a one-to-one correspondence. Since the elements are defined and the proof stress of the beam-column joint can be evaluated by calculation, and the influence of each member constituting the beam-column joint can be grasped, the improvement of the members constituting the beam-column joint can be studied. It becomes possible to carry out easily, and optimization of each member can be aimed at.
