Description

【0001】
【発明の属する技術分野】
本発明は、CADを利用した建築物の構造設計、特に2階建以下の軸組み木造住宅の構造設計において、設計壁量や、必要壁量に対する設計壁量の割合を示す安全率、また、耐力壁の配置バランスを示す偏心率を耐力壁の入力毎にリアルタイムでカウント表示し、さらに、柱の引抜力をも算定する、設計途上の建築物の構造につき総合的に判定する技術に属するものである。
【0002】
【従来の技術】
2階建以下の軸組み木造の構造設計において、壁量計算と耐力壁配置バランス等は必須のチェック項目であり、従来、これらはこれらの算出及びその適否は既存のマニュアルに従って設計士が人手で行っており、また、壁量計算や安全率、偏心率の算出、柱の引抜力の算定等を行う場合には表計算プログラムソフトや構造計算プログラムを使って行われてきた。
【0003】
【発明が解決しようとする課題】
しかしながら、上記のように人手で行う場合には、算出に至る演算過程が複雑で長時間を要し、また、表計算プログラムソフトを利用する場合においては、当該ソフトに計算をさせる前段階として、存在する柱の座標、耐力壁の壁倍率等を設計毎にシステムへ数値を入力することが必要となり、さらに、隅柱か隅柱以外の柱かの別を認識させるなど、その準備作業に多大な時間と労力を要していた。
【0004】
また、従来の構造計算プログラムによる場合には、耐力壁及び柱や梁等の部材を全て入力して初めて壁量及び偏心率等がチェックされるので、既に設計した内容が適正でない場合には、再度、同様の入力作業が求められることとなり、設計作業の完了までに多くの時間と労力を要してきた。
本願は、上記のような煩わしさを伴わずに、耐力壁をCAD入力する度にリアルタイムで設計壁量や、必要壁量に対する設計壁量の割合である安全率、また、偏心率をカウント表示させ、さらに、柱の引抜力の算定に至るまで、当該値が適正か否かを設計作業途上においても容易に確認し得るシステムを開発しようというものである。

【0011】
【発明の実施の形態】
図1は、本発明の設計構造総合判定システムの構成図である。この図において、中央処理装置(1)は、バス線(8)を介してキーボードやマウス等の入力装置(2)、表示装置(3)、ROM(リードオンメモリー)(5)、RAM(ランダムアクセスメモリー)(6)、HDD(ハードディスク)(7)と制御信号や格納データの授受、そして各種の処理を行う。
ROM(5)は中央処理装置(1)において実行される本システムに係るプログラムを格納し、RAM(6)は中央処理装置(1)の補助メモリとして使用する。また、HDD(7)は本システムで作成した各種ファイル及び各種のデータを格納する。
【0012】
なお。本システムは上記の構成に限られるものでなく、他の既知の構成によってもよく、また、CD−ROM等のコンピュータ読み取り可能な記録媒体に本システムに係るプログラムやファイル等を記録して、他のコンピュータにインストールして利用できるほか、サーバ装置を利用し、ネットワークを介して他のコンピュータのメモリへダウンロードすることも可能である。
【0013】
耐力壁の設計壁量とは、設計対象となっている建築物の構造上、支えになるような一定の強度を持つ壁の長さのことであり、建築基準法で必要とされる数値を上回ることが求められる。そして、本システムにおいては、耐力壁の入力作業により累積されたX軸方向(建築物の間口方向)、Y軸方向(建築物の奥行き方向)の耐力壁の合計壁量を指すものである。
また、必要に応じて、横架材に達していない面材(準耐力壁)や腰壁による壁量との合算とする。なお、必要に応じて、耐力壁線毎の壁量を算出し、画面上に表示する機能も有する。
【0014】
建築物特定条件とは、壁量計算の基礎となる条件であり、建設地や当該建築物の目標とする品確法耐震等級1〜3、そして耐風等級1、2等その他の条件であり、また、当該建築物自体に関する条件として、基礎の高さ、1、2階の階高といった建築物の仕様に関する条件等である。そして、当該条件を考慮した係数が本システムにプログラムされた算出式において、条件設定に伴い、反映されるものである。
【0015】
外形ラインとは、耐力壁が周っている建物の1層、2層の外壁ラインをいい、必要に応じて袖壁をも含むものである。
【0016】
要素とは、壁量計算に必要な要素である屋根、床、バルコニーをいい、前述の外壁ラインを基に入力するが、必要に応じて外部付帯、特殊荷重をも含む。
【0017】
安全率とは、必要壁量に対する設計壁量の割合をいい、耐力壁の入力データに基づき本システムのプログラムされた算出手段により求められる。本システムの使用者は、1.0≦安全率≦2.0を適正範囲と認識し、この範囲外の結果に至った場合には耐力壁の入力作業をやり直す。なお、本システムは耐力壁の入力毎に自動的に設計壁量及び安全率を算出する。
【0018】
偏心率とは、建築物のねじれに対する強さの目安となる数値である。本システムは、前述の建築物特定条件、外形ライン、要素の入力、そして、耐力壁の入力データに基づき、当該建築物につき、重心位置、剛心位置を認識し、両者間の距離である偏心距離を求め、さらに弾力半径を自動的に算出する。偏心率は、本システムのプログラムされた算出手段により、周知の算出式(偏心距離/弾力半径)により求められる。
【0019】
また、耐力壁の種類及び各壁倍率は、2.5/面材、2.0/片筋違、2.0×2/両筋違、2.5×2/面材W、0.5〜5.0/その他の耐力壁、と耐力壁の種類毎に設定されており、耐力壁の種類選定に伴って本システムにより自動的に認識され、その後の壁量計算の基礎とされる。
【0020】
なお、本システムによる算出又は算定結果は、CAD画面上に耐力壁、準耐力壁配置図とともに、数値表示され、また、算出又は算定結果一覧として、管柱毎に算出式又は算定式とともに表示する。
【0021】
[実施例1]
本発明の第1の実施例を図1〜図3に基づいて説明する。
図1は本発明のシステムを示すハードウエア構成図、図2は本発明による作業手順を示すフロー図、図3は耐力壁入力画面を示す図である。
【0022】
(1)は中央処理装置、(2)は入力装置、(3)は表示装置、(4)は出力装置、(5)はROM、(6)はRAM、(7)はHDD、(8)はバス線、(9)は耐力壁選択ウィンドウ、(10)は壁倍率確認・選択ウインドウ、(11)は壁量等確認ウインドウ、(12)は面材、(13)は片筋違、(14)は両筋違、(15)は重心、(16)は剛心、(P)は1層外形ラインである。
【0023】
以下、操作手順を図2に従って説明する。まず、操作画面上で、耐力壁の必要壁量及び設計壁量の算出の基礎の一つとなる条件を選択入力する(S101)。当該条件項目は、建設地、品確法耐震等級1〜3の別、耐風等級1、2の別、また、建築物自体に関する条件として、基礎の高さ、1、2階の階高といった建築物の仕様である。
建築物自体の条件は、予め住宅モデルとリンクさせ、住宅モデル選択と同時に必要条件がシステムに反映するものとし、必要に応じて変更し得る態様としてよい。
【0024】
上記、条件入力の後、耐力壁が周っている建物の1層、2層の外壁ラインである、外形ラインの入力を行う(S102)。本実施例における1層の外形ラインは図3に示す点線(P)である。
【0025】
次に、必要壁量の計算の基礎となる要素である、屋根、床、バルコニーの入力を行う(S103)。当該入力は、前述の外壁ラインを基に入力するが、必要に応じて外部付帯、特殊荷重をも含む。
【0026】
次に、耐力壁の入力作業を、図3に基づき説明する。
まず、耐力壁選択ウインドウ(9)に表示されている面材、片筋違、両筋違い、面材W、その他の耐力壁の中から、入力しようとする耐力壁の種類を選択するが、この時、耐力壁の種類選択と同時に、壁倍率確認・選択ウインドウ(10)に、選択された耐力壁の種類をシステムが認識して自動的に表示することにより、使用者は当該倍率を確認する。
なお、条件入力(S101)〜要素入力(S103)の入力結果に基づき、システムにより必要壁量が算出され、壁量等確認ウインドウ(11)中に表示されている。本実施例においては、X方向(建築物の間口方向)、Y方向(建築物の奥行き方向)に夫々35.60である。
【0027】
次に、使用者は1層外形ライン(P)を基に、面材(12)、片筋違(13)、両筋違(14)を入力する(S104)が、この時、壁量等確認ウインドウ(11)中に、耐力壁の入力毎に設計壁量が、X方向、Y方向の夫々について算出され、累積されるため、使用者は自己の設計が壁量不足であるのか、過剰設計であるのかを逐次確認しながら作業可能となる。
【0028】
また、設計壁量の算出とともに、安全率がX方向、Y方向の夫々について算出され、壁量等確認ウインドウ(11)中に表示される。安全率は必要壁量に対する設計壁量の割合として求められ、耐力壁の入力データに基づき本システムのプログラムされた算出手段により求められる。使用者は、当該安全率の数値が1.0〜2.0の適正範囲にあるか否かを耐力壁の入力作業に伴い認識し、万一、当該適正範囲外の結果に至った場合には耐力壁の入力作業をやり直す。本実施例においては、X方向に1.62、Y方向に1.92であるため、適正範囲内にあると、使用者は認識できる。
【0029】
また、本システムにおいては、偏心率を耐力壁の入力作業に伴い、壁量等確認ウインドウ(11)中に表示する。偏心率は建築物のねじれに対する強さの目安となる数値であり、前述の建築物特定条件、外形ライン、要素の入力、そして、耐力壁の入力データに基づき、当該建築物の重心位置、剛心位置を認識し、両者間の距離である偏心距離を求め、さらに弾力半径を自動的に算出することにより、本システムのプログラムされた算出手段により、周知の算出式(偏心距離/弾力半径)により求められ、表示される。
【0030】
重心位置は、建築物の一隅を原点としたときの重心座標であり、間取りにより変化する。また、剛心位置は、建築物の剛性からみた場合の中心となる位置の座標であり、仮に南側に筋かいが多ければ、剛心位置は南側に偏る。偏心距離は両位置間の距離である。また、弾力半径とは、剛心周りのねじり剛性の数値を各方向の水平剛性の数値で除した数値の平方根であり、これらの算出、及び位置の認識はすべて本システムにプログラムされた手段により行われるものである。
【0031】
以上のように、本実施例によれば、使用者は、複雑な演算を人手で行うことなく、また、既存の表計算プログラムソフトに計算させる前段階の準備として、
柱の座標や耐力壁の壁倍率等を設計毎にシステムへ数値入力することも必要なくなり、さらに、耐力壁の入力作業に伴ってリアルタイムで設計壁量、安全率、偏心率を確認しながら、構造設計ができることから、耐力壁の入力作業に集中することができ、当該作業を完了するまでに要する時間を大幅に短縮することが可能となる。
【0032】
[実施例2]
本発明の第2の実施例を図2、図4を参照しながら説明する。
図4は準耐力壁入力画面を示す図であり、図中、(17)は準耐力壁Aを示す。なお、その他の数字、記号は実施例1と同様の対象を示す。
【0033】
本実施例においては、垂れ壁や腰壁といった準耐力壁等の内、面材の高さが横架材間の8割以上の準耐力壁である準耐力壁A(17)を入力し、前述の耐力壁の壁量に準耐力壁の壁量をも考慮した安全率を確認する。
【0034】
先の実施例の作業に引き続き、準耐力壁を入力する場合(S106)、表示画面を準耐力壁入力画面に切替え(図4)、耐力壁の入力と同様、耐力壁選択ウインドウ(9)より準耐力壁の種類を選択する。この選択に伴い、準耐力壁の種類に対応して設定されている壁倍率が、壁倍率確認・選択ウインドウ(10)に表示される。また、先の条件入力時に選択(S101)した耐震等級3、耐風等級2との情報が当該画面上に表示される。
【0035】
壁量等確認ウインドウ(11)中に、入力した準耐力壁データに従って、設計壁量が算出、表示され、かつ、先の耐力壁の設計壁量に加算して合計として表示される。
【0036】
また、先の条件入力時に選択(S101)した耐震等級3、耐風等級2との情報に基づき、本システムは必要壁量を、X方向、Y方向の夫々について、当該建築物の耐震による必要壁量、耐風による必要壁量をプログラムされた手段により、算出表示する。
さらに、耐力壁量と準耐力壁量の合計壁量が必要壁量を上回っているか否かの安全率を算出する。この場合、本システムは、耐震による必要壁量と耐風による必要壁量の大きい値を自動的に認識し、当該値を基に安全率を算出する。本実施例においては、X方向の安全率が1.28(66.50/52.15)、Y方向の安全率が1.60(83.50/52.15)と表示されており、適正な範囲内であることが確認できる。
【0037】
本実施例においても、準耐力壁の入力とともに、リアルタイムで安全率の算出が行われるため、使用者は当該値を確認しながら、準耐力壁の入力作業をおこなうことができ、別途の計算や、演算に必要なデータの入力作業等は不要である。
【0038】
[実施例3]
本発明の第3の実施例を図2、図5、図6を参照しながら説明する。
図5は管柱入力画面を示す図であり、図6は柱引抜力算定画面を示す図で、図中、(18)は柱選択ウインドウ、(19)は管柱、(Q)は床面外周ラインを示す。
【0039】
本実施例は、床面外周ライン、耐力壁、準耐力壁の入力後に、管柱(19)を層毎に入力し、入力した各管柱につき柱引抜力を算定し、CAD画面上に表示し、確認するものである。
【0040】
図2に示す要素入力(S103)段階で、床面外周ライン(Q)を入力し、その後、耐力壁、準耐力壁を入力した後に、管柱入力画面(図5)において、管柱(19)を入力する。
まず、柱選択ウインドウ(18)により、管柱(下)つまり、1層の管柱(19)を選択する。そして、「配置ボタン」をクリックした後、CAD画面上にマウス等入力装置により、所望の位置に管柱を配置する。同様の作業を2層においても行う。
また、前記耐力壁の入力時には、自動的に当該耐力壁の横に管柱が配置され、CAD画面上に表示される。また、自動配置されない、耐力壁部でない柱についても引抜力算定に関係する独立した管柱として入力し、画面上に表示される。
【0041】
入力された管柱は、出隅部に配置されたものか、あるいは出隅部以外に配置されたものかを本システムが自動的に認識すると同時に、柱引抜力算定の基礎となる、当該管柱に接する耐力壁の壁倍率も認識する。
【0042】
管柱入力後、「耐力壁入力画面へ」ボタンをクリックし、図3に示す耐力壁入力画面中の「柱引抜力算定ボタン」をクリックすると、図6に示すように管柱毎に引抜力が表示され、使用者は当該画面上で、引抜力を確認することができる。なお、図6は例示であるため一部の管柱にしか引抜力が表示されていないが、実際には、全ての管柱に数値が表示されている。
なお、プラン変更等により耐力壁を再入力した場合、再入力された耐力壁の壁倍率等を再認識し、柱引抜力の算定を再び行い、当該画面上の当該管柱近傍に再表示される。
【0043】
[実施例4]
本発明の第4の実施例を図5、図7を参照しながら説明する。
図7は引抜力詳細表示画面を示す図であり、1階のY方向につき、各管柱の柱引抜力を示したものである。
【0044】
本実施例は、各管柱にかかる引抜力の算定過程を詳細表示し、構造検討書等、行政庁への提出書類としても利用可能とするものである。
【0045】
図5中「柱引抜力算定ボタン」をクリックすると、図7に示すように引抜力詳細表示画面が表示される。なお、当該算定方法は周知の算定式を利用するものであるが、独自の係数を考慮して、当該柱引抜力を示す値の信頼性をより高めることも考えられる。
図中、「階」は1階、2階の別、「方向」はX方向(建築物の間口方向)、Y方向(建築物の奥行き方向)の別、「X座標」「Y座標」は各管柱の配置座標を示す。
【0046】
また、「A1」は管柱の両面における耐力壁の倍率の差(片側のみ耐力壁が取り付く場合には、当該耐力壁の壁倍率)の数値を示し、筋違を設けた耐力壁の場合には、各筋違の位置、種類に応じて補正値を考慮している。「B1」は周辺の部材による押え(曲げ戻し)の効果を表す係数で、出隅の柱においては0.8、その他の柱においては0.5とする。
【0047】
「A2」は管柱に連続する2階管柱の両側における耐力壁の倍率の差(片側のみ耐力壁が取り付く場合には、当該耐力壁の壁倍率)の数値を示し、筋違を設けた耐力壁の場合には、各筋違の位置、種類に応じて補正値を考慮している。「B2」は2階周辺の部材による押え(曲げ戻し)の効果を表す係数で、2階の出隅の柱においては0.8、その他の柱においては0.5とする。
【0048】
「NL」は鉛直荷重による押えの効果を示す係数で、2階建ての1階の場合、出隅の管柱においては1.0、その他の管柱においては1.6とする。また、2階建ての2階及び平屋建ての場合は出隅の管柱は0.4、その他の管柱は0.6とする。
このようにして、接合金物の選択の基準値を示す「N値」が求められ、当該「N値」に所定の係数5.3を乗じた結果が、柱引抜力(kN)である。
【0049】
当該算定結果が適当でないと使用者が判断した場合には、管柱の再入力、あるいは、耐力壁、準耐力壁を再入力すれば、本システムが当該再入力データを再認識し、自動的に再算定する。そして満足する算定結果に至った場合には、印刷し、構造検討書等、行政庁への提出書類等に利用することができる。
本実施例によれば、使用者は、改めて行政庁等への書類の作成業務等に時間を取られることなく、建築物の構造設計作業に集中することができる。
【0050】
【発明の効果】
以上、述べてきた通り、本発明によれば、人手で行っていた場合のように、長時間をかけての壁量計算に伴う複雑な演算を行うことなく、また、表計算プログラムソフトを利用する場合の前段階としての必要情報としての数値入力も不要となり、さらに、柱や梁等に至るまで全ての部材を入力することなく、耐力壁の入力作業と並行して、設計壁量、必要壁量に対する設計壁量の割合を示す安全率、耐力壁の配置バランスを示す偏心率を設計画面上でリアルタイムで確認できることから、作業効率が飛躍的に改善されるものである。さらに、システムを利用することから、設計データを行政庁等への提出書類へ反映することも容易となり建築物の構造設計作業全体としての処理が、正確、かつ、迅速に行えるものである。

It is specification of.
The conditions of the building itself may be linked to the house model in advance, and the necessary conditions may be reflected in the system simultaneously with the selection of the house model, and may be changed as necessary.
[0024]
After the above condition input, an outline line, which is an outer wall line of one layer or two layers of a building around a load-bearing wall, is input (S102). The outer layer of one layer in this embodiment is a dotted line (P) shown in FIG.

Next, a roof, a floor, and a balcony, which are elements serving as a basis for calculating the required wall amount, are input (S103). The input is made on the basis of the above-mentioned outer wall line, but also includes an external accessory and a special load as necessary.
[0026]
Next, the input operation of the bearing wall will be described with reference to FIG.
First, the type of the load-bearing wall to be input is selected from among the face material, the single streak difference, the two streak differences, the face material W, and the other load-bearing walls displayed in the load-bearing wall selection window (9). At this time, at the same time as selecting the type of bearing wall, the system recognizes the selected type of bearing wall and automatically displays the selected type in the wall magnification confirmation / selection window (10), so that the user confirms the magnification. .
The required wall amount is calculated by the system based on the input results of the condition input (S101) to the element input (S103) and is displayed in the wall amount etc. confirmation window (11). In the present embodiment, it is 35.60 in the X direction (the frontage direction of the building) and the Y direction (the depth direction of the building).
[0027]
Next, the user inputs a face material (12), a single strut (13), and a double streak (14) based on the one-layer outline line (P) (S104). During the confirmation window (11), the design wall amount is calculated and accumulated for each of the X-direction and the Y-direction for each load-bearing wall input, so that the user can determine whether his or her design is insufficient or excessive. Work can be performed while sequentially checking whether or not the design is successful.
[0028]
Further, the safety factor is calculated for each of the X direction and the Y direction together with the calculation of the design wall amount, and is displayed in the wall amount etc. confirmation window (11). The safety factor is obtained as a ratio of the design wall amount to the required wall amount, and is obtained by the programmed calculating means of the present system based on the input data of the load-bearing wall. The user recognizes whether or not the numerical value of the safety factor is in an appropriate range of 1.0 to 2.0 in accordance with the input operation of the load-bearing wall, and in a case where the result of the safety factor is out of the appropriate range.

In the present system, the eccentricity is displayed in the wall amount etc. confirmation window (11) in accordance with the input operation of the load bearing wall. The eccentricity is a numerical value that is a measure of the strength of a building against torsion. Based on the above-mentioned building identification conditions, outline lines, input of elements, and input data of load-bearing walls, the center of gravity of the building, By recognizing the center position, obtaining the eccentric distance that is the distance between the two, and automatically calculating the elastic radius, the known calculating formula (eccentric distance / elastic radius) can be calculated by the programmed calculating means of the present system. Is required and displayed.
[0030]
The position of the center of gravity is the coordinates of the center of gravity when one corner of the building is set as the origin, and changes depending on the layout. Further, the rigidity position is a coordinate of a central position when viewed from the rigidity of the building. If there is a large amount of bracing on the south side, the rigidity position is shifted to the south side. The eccentric distance is the distance between the two positions. The elastic radius is the square root of the value obtained by dividing the value of the torsional stiffness around the center of gravity by the value of the horizontal stiffness in each direction, and all of these calculations and position recognition are performed by means programmed in this system. Is what is done.
[0031]
As described above, according to the present embodiment, the user does not need to perform complicated calculations manually, and as preparation for a pre-stage for causing existing spreadsheet software to perform calculations.
It is no longer necessary to input numerical values such as column coordinates and wall magnification of bearing walls to the system for each design.In addition, while checking the design wall amount, safety factor, and eccentricity in real time with the input work of bearing walls, Since the structural design can be performed, it is possible to concentrate on the input operation of the load-bearing wall, and it is possible to greatly reduce the time required to complete the operation.
[0032]
[Example 2]
A second embodiment of the present invention will be described with reference to FIGS.
FIG. 4 is a diagram showing a quasi-bearing wall input screen, in which (17) indicates a quasi-bearing wall A. Other numbers and symbols indicate the same objects as in Example 1.
[0033]
In this embodiment, among the quasi-bearing walls such as the hanging wall and the waist wall, the quasi-bearing wall A (17), which is a quasi-bearing wall having a face material height of 80% or more between the horizontal members, is input. The safety factor is confirmed in consideration of the wall amount of the quasi-bearing wall as well as the wall amount of the above-mentioned bearing wall.
[0034]
When the quasi-bearing wall is input following the work of the previous embodiment (S106), the display screen is switched to the quasi-bearing wall input screen (FIG. 4). Select the type of semi-bearing wall. With this selection, the wall magnification set corresponding to the type of the quasi-bearing wall is displayed in the wall magnification confirmation / selection window (10). In addition, the information of the seismic class 3 and the wind class 2 selected (S101) at the time of the previous condition input is displayed on the screen.
[0035]
In the wall amount confirmation window (11), the design wall amount is calculated and displayed in accordance with the input quasi-bearing wall data, and is added to the design wall amount of the previous bearing wall and displayed as a total.
[0036]
Further, based on the information of the seismic class 3 and the wind class 2 selected at the time of inputting the above conditions (S101), the present system determines the required wall amount in each of the X direction and the Y direction. The amount and the required wall amount due to wind resistance are calculated and displayed by the programmed means.
Further, a safety factor for calculating whether or not the total wall amount of the load-bearing wall amount and the quasi-bearing wall amount exceeds the required wall amount is calculated. In this case, the system automatically recognizes a large value of the required wall amount due to earthquake resistance and the required wall amount due to wind resistance, and calculates the safety factor based on the values. In this embodiment, the safety factor in the X direction is displayed as 1.28 (66.50 / 52.15), and the safety factor in the Y direction is displayed as 1.60 (83.50 / 52.15). It can be confirmed that it is within the range.
[0037]
Also in the present embodiment, since the calculation of the safety factor is performed in real time together with the input of the quasi-bearing wall, the user can perform the input work of the quasi-bearing wall while checking the value, and can perform a separate calculation or It is not necessary to input data necessary for calculation.
[0038]
[Example 3]
A third embodiment of the present invention will be described with reference to FIGS.
FIG. 5 is a diagram showing a pipe column input screen, and FIG. 6 is a diagram showing a column pull-out force calculation screen, where (18) is a column selection window, (19) is a tube column, and (Q) is a floor surface. The outer peripheral line is shown.
[0039]
In this embodiment, after inputting the floor outer peripheral line, the bearing wall, and the quasi-bearing wall, the column (19) is input for each layer, the column pull-out force is calculated for each input column, and displayed on the CAD screen. And confirm it.
[0040]
In the element input (S103) stage shown in FIG. 2, a floor outer peripheral line (Q) is input, and after inputting a load-bearing wall and a quasi-load-bearing wall, the pipe column (19) is displayed on the pipe column input screen (FIG. 5). ).
First, a tube column (lower), that is, a single-layer tube column (19) is selected by the column selection window (18). Then, after clicking the "placement button", the pipe column is placed at a desired position on the CAD screen by using an input device such as a mouse. The same operation is performed for two layers.
In addition, when inputting the load-bearing wall, a pipe column is automatically arranged beside the load-bearing wall and displayed on the CAD screen. Columns that are not automatically arranged and are not load-bearing walls are also input as independent pipe columns related to the calculation of the pull-out force and displayed on the screen.
[0041]
The system automatically recognizes whether or not the input column is located at the corner or outside the corner. The wall magnification of the load-bearing wall in contact with the column is also recognized.
[0042]
After inputting the pipe columns, click the “To load-bearing wall input screen” button, and then click the “Column pull-out force calculation button” in the load-bearing wall input screen shown in FIG. 3, and as shown in FIG. Is displayed, and the user can confirm the pull-out force on the screen. In addition, since FIG. 6 is an example, the pull-out force is displayed on only some of the pipe columns, but actually, numerical values are displayed on all of the pipe columns.
If the load-bearing wall is re-entered due to a plan change, the wall magnification etc. of the re-input load-bearing wall is re-recognized, the column pull-out force is calculated again, and displayed again near the pipe column on the screen. You.
[0043]
[Example 4]
A fourth embodiment of the present invention will be described with reference to FIGS.
FIG. 7 is a diagram showing a detailed pull-out force display screen, and shows the column pull-out force of each pipe column in the Y direction on the first floor.
[0044]
In this embodiment, the calculation process of the pull-out force applied to each pipe column is displayed in detail, and can be used as a document to be submitted to the administrative agency such as a structural examination report.
[0045]
When the "column pullout force calculation button" in FIG. 5 is clicked, a pullout force detail display screen is displayed as shown in FIG. Although the calculation method uses a well-known calculation formula, it is conceivable that the reliability of the value indicating the column pull-out force is further increased in consideration of a unique coefficient.
In the figure, “floor” is the first floor or second floor, “direction” is the X direction (frontage direction of the building), Y direction (the depth direction of the building), “X coordinate” and “Y coordinate” are The arrangement coordinates of each pipe column are shown.
[0046]
“A1” indicates the numerical value of the difference in the magnification of the load-bearing wall on both sides of the pipe column (when the load-bearing wall is attached to only one side, the wall magnification of the load-bearing wall). Considers the correction value according to the position and type of each strut. “B1” is a coefficient indicating the effect of pressing (bending back) by the peripheral members, and is set to 0.8 for the pillar at the protruding corner and to 0.5 for the other pillars.
[0047]
"A2" indicates the numerical value of the difference in the magnification of the load-bearing wall on both sides of the second-floor pipe column that is continuous with the pipe column (when only one side has a load-bearing wall, the wall magnification of the load-bearing wall). In the case of a load-bearing wall, a correction value is considered according to the position and type of each streak. “B2” is a coefficient representing the effect of holding down (returning) by members around the second floor, and is set to 0.8 for the column at the corner of the second floor and 0.5 for the other columns.
[0048]
"NL" is a coefficient indicating the effect of holding down by a vertical load. In the case of a two-story first floor, it is set to 1.0 for a pipe column at an outer corner and 1.6 for other pipe columns. In the case of a two-story two-story or one-story house, the outer diameter of the column is 0.4 and the other columns are 0.6.
In this way, the “N value” indicating the reference value for selecting the metal joint is obtained, and the result of multiplying the “N value” by the predetermined coefficient 5.3 is the column pullout force (kN).
[0049]
If the user determines that the calculation result is not appropriate, re-enter the pipe column, or re-enter the load-bearing wall or semi-bearing wall, the system will recognize the re-input data again and automatically Is recalculated. When a satisfactory calculation result is reached, it can be printed out and used for documents to be submitted to the administrative agency, such as a structural examination report.
According to the present embodiment, the user can concentrate on the structural design work of the building without taking the time to prepare documents for the administrative agency or the like again.
[0050]
【The invention's effect】
