Abstract
Description
本発明は、１階が鉄筋コンクリート壁式構造であり、２階及び３階が木造である混構造計算方法及び計算システムに関する。 The present invention relates to a mixed structure calculation method and calculation system in which the first floor has a reinforced concrete wall structure, and the second and third floors are wooden.
近年、住宅等の小規模な建築物において、１階部分を鉄筋コンクリート造、２階以上を木造とするような、所謂「混構造」の建築物が建てられるようになった。このような混構造建築物の内、１階部分を鉄筋コンクリート造りとする混構造住宅は、２００７年の改正建築基準法の施行により、構造計算が義務付けられている。 In recent years, so-called “mixed structure” buildings have been built in which small-scale buildings such as houses are made of reinforced concrete on the first floor and wooden on the second and higher floors. Among such mixed structure buildings, the structural calculation is required for the mixed structure houses whose first floor is made of reinforced concrete due to the enforcement of the revised Building Standard Act of 2007.
このような混構造の建築物の構造計算を行う際、木造階については従来の計算ソフト等で計算できるが、鉄筋コンクリート造りの構造計算ソフトは主たるものがビル等の巨大建造物用であり、小規模建築用のものが存在していない。そのため、住宅等の小規模な混構造建築物を設計する際には、鉄筋コンクリート造である階の計算のみを大規模建築専門業者に個別に依頼していた。 When calculating the structure of such a mixed structure building, the wooden floor can be calculated with conventional calculation software, etc., but the reinforced concrete structure calculation software is mainly used for large buildings such as buildings, and so on. There is no one for a scale building. For this reason, when designing a small-scale mixed structure building such as a house, only large-scale construction specialists were individually requested to calculate only the floors made of reinforced concrete.
例えば、２階ないし３階が木造、１階がコンクリート（ＲＣ）壁式構造の混構造住宅において構造計算を行う場合は、以下の手順となる。
（１）屋根からの荷重で３階木造部分の構造を評価する。
（２）３階までの荷重（屋根の荷重＋３階の荷重）で２階木造部分の構造を評価する。
（３）２階までの荷重（屋根の荷重＋３階の荷重＋２階の荷重）で１階ＲＣ壁式部分の構造を評価する。
For example, when structural calculation is performed in a mixed structure house in which the second to third floors are wooden and the first floor is a concrete (RC) wall structure, the following procedure is performed.
(1) Evaluate the structure of the 3rd floor wooden part by the load from the roof.
(2) Evaluate the structure of the second-floor wooden part with the load up to the third floor (roof load + third floor load).
(3) The structure of the 1st floor RC wall type part is evaluated by the load up to the 2nd floor (roof load + 3rd floor load + 2nd floor load).
従来では、上記（１）、（２）の計算を木造用、（３）の計算をＲＣ壁式用の構造計算ソフト等で行っていた。その際、（３）では、壁、床、柱から伝達される木造階の荷重を平均してＲＣ壁式構造ソフトに手入力していた。 Conventionally, the calculations of (1) and (2) have been performed for wooden structures, and the calculation of (3) has been performed by structural calculation software for RC wall type. At that time, in (3), the load on the wooden floor transmitted from the walls, floors, and pillars was averaged and manually input to the RC wall type structure software.
この場合、木造階と鉄筋コンクリート造階を一貫して計算できないため、木造階のデータをコンクリート構造計算ソフトへ移行する際の修正入力が、フォーマットや手法の違いにより別途発生しており、データ修正時の手間も大変であった。
また、上階木造部の全重量を下階のＲＣ部に平均して載荷させていたため、下階の部材にかかる正確な荷重を算出することが困難であった。
In this case, the wooden floor and the reinforced concrete floor cannot be calculated consistently, so correction input when moving the wooden floor data to the concrete structure calculation software is generated separately due to the difference in format and method. The trouble of was also difficult.
In addition, since the entire weight of the upper floor wooden part is loaded on the RC part of the lower floor on average, it is difficult to calculate an accurate load applied to the members of the lower floor.
上記のような事情より、混構造の建築物について、１階部分を木造住宅構造の一部としてフォーマット、手法を合わせ、連携計算できるような方法が望まれていた。 In view of the above circumstances, there has been a demand for a method capable of performing a cooperative calculation for a mixed structure building by combining the format and method with the first floor part as a part of the wooden house structure.
本発明は、混構造である建築物の構造計算を行う際に、建築物の情報の入力が容易であり、構造毎の構造計算書及び建築物全体の構造計算概要書をまとめて出力することを可能とする混構造計算方法及び計算システムを提供することを目的とする。 When performing the structural calculation of a building having a mixed structure, the present invention makes it easy to input building information, and outputs the structural calculation sheet for each structure and the structural calculation summary for the entire building. An object of the present invention is to provide a mixed structure calculation method and a calculation system that can perform the above.

However, these embodiments are described in order to help understanding of the present invention, and are intended to limit the present invention to the described embodiments. It is obvious that there is nothing.
本実施形態に係る混構造計算方法は、１階が鉄筋コンクリート壁式構造であり、２階及び３階が木造である混構造の建築物の構造計算を行うためのシステムである。
該方法は、建築物の設計データに基づいて、建築物の屋根の荷重で３階部分の構造を評価し、
屋根の荷重及び３階の荷重で２階部分の構造を評価し、２階までの木造部の柱、壁及び床の荷重を１階の区画毎に集計し、１階の鉄筋コンクリート造の部材にかかる荷重を算出し、１階部分の構造を評価することを特徴とする混構造計算方法である。
The mixed structure calculation method according to the present embodiment is a system for calculating the structure of a mixed structure building in which the first floor is a reinforced concrete wall structure and the second and third floors are wooden.
The method evaluates the structure of the third floor part by the load of the building roof based on the design data of the building,
Evaluate the structure of the second floor part by the load of the roof and the load of the third floor, and total the pillar, wall and floor loads of the wooden part up to the second floor for each section of the first floor, and make it a member of the reinforced concrete structure of the first floor It is a mixed structure calculation method characterized by calculating such a load and evaluating the structure of the first floor portion.
本実施形態に係る混構造計算方法及び計算システムは、混構造である建築物を計算するためのものである。
ここで、混構造とは、木造と鉄骨造、鉄骨造と鉄筋コンクリート造のような、階層毎に異なる構造方式を採用した建築物である。本発明に係る混構造計算システム及び計算方法は、特に、１階が鉄筋コンクリート壁式構造であり、２階及び３階が木造である混構造建築物に好ましく用いることができる。
The mixed structure calculation method and calculation system according to the present embodiment are for calculating a building having a mixed structure.
Here, the mixed structure is a building that adopts a different structural method for each layer, such as a wooden structure and a steel structure, and a steel structure and a reinforced concrete structure. The mixed structure calculation system and calculation method according to the present invention can be preferably used for a mixed structure building in which the first floor is a reinforced concrete wall structure and the second and third floors are wooden.
図１は、混構造建築物の計算における、従来の構造計算と本発明に係る構造計算の手順を説明する図である。 FIG. 1 is a diagram for explaining a procedure of conventional structural calculation and structural calculation according to the present invention in calculation of a mixed structure building.
図１に示すように、従来の構造計算においては、先ず利用者が木造階の計算ソフトなどにより木造階についてのみ構造計算を行い、木造階の構造計算書（Ａ）及び木造階から下階への荷重伝達図を出力する。そして、該荷重伝達図から荷重の状態を確認し、下階の鉄筋コンクリート造階に適用するために荷重を平均化する。再び、上記の木造階の計算ソフトとは異なる手段で鉄筋コンクリート造階の構造計算を行い、鉄筋コンクリート造階の構造計算書（Ｂ）を出力する。 As shown in FIG. 1, in the conventional structural calculation, the user first performs the structural calculation only for the wooden floor by using the wooden floor calculation software, etc., and from the wooden floor to the structural calculation sheet (A) and from the wooden floor to the lower floor. The load transmission diagram of is output. Then, the state of the load is confirmed from the load transmission diagram, and the load is averaged for application to the reinforced concrete floor of the lower floor. Again, the structural calculation of the reinforced concrete floor is performed by means different from the wooden floor calculation software, and the structural calculation sheet (B) of the reinforced concrete floor is output.
さらに、各階の情報に基づいて、木造階及び鉄筋コンクリート造階の構造計算概要書（Ｃ）を別途作成する。そして、確認申請のため、木造階及び鉄筋コンクリート造階の構造計算書（Ａ、Ｂ）及び構造計算概要書（Ｃ）を審査機関へ提出する。
このように従来の混構造計算においては、構造の異なる階層の計算を別個に行っていた。
Further, based on the information of each floor, a structural calculation summary document (C) for the wooden floor and the reinforced concrete floor is separately created. Then, for the confirmation application, the structural calculation sheets (A, B) and the structural calculation summary sheet (C) of the wooden floor and the reinforced concrete floor are submitted to the examination organization.
As described above, in the conventional mixed structure calculation, the calculation of the layers having different structures is performed separately.
本発明に係る混構造計算システムにおいては、利用者が、構造の異なる階層のデータをまとめて入力できる。そして、構造計算は一つのシステム内で処理されるため、木造階の構造計算書（Ａ）、鉄筋コンクリート造階の構造計算書（Ｂ）及び構造計算概要書（Ｃ）がまとめて出力される。 In the mixed structure calculation system according to the present invention, a user can collectively input data of layers having different structures. Since the structural calculation is processed in one system, the wooden floor structural calculation sheet (A), the reinforced concrete floor structural calculation sheet (B), and the structural calculation summary sheet (C) are output together.
このように本実施形態に係る混構造計算方法においては、混構造である建築物の構造計算を行う際に、建築物の情報の入力を一括して行えるため、容易に扱うことができる。
また、従来別途に出力されていた構造毎の構造計算書及び建築物全体の構造計算概要書をまとめて出力することが可能である。
As described above, in the mixed structure calculation method according to the present embodiment, when the structure calculation of a building having a mixed structure is performed, the building information can be input in a lump, so that it can be easily handled.
In addition, it is possible to collectively output a structural calculation sheet for each structure and a structural calculation summary sheet for the entire building that have been output separately.
次に、本実施形態に係る混構造計算システム及び計算方法の計算手段について説明する。 Next, calculation means of the mixed structure calculation system and calculation method according to the present embodiment will be described.
本実施形態に係る混構造計算方法では、ＣＡＤ等の建築物の設計データに基づいて、建築物の屋根の荷重で３階部分の構造の評価を行う。次いで、屋根の荷重及び３階の荷重で２階部分の構造の評価を行う。 In the mixed structure calculation method according to the present embodiment, the structure of the third floor portion is evaluated by the load on the roof of the building based on the design data of the building such as CAD. Next, the structure of the second floor portion is evaluated by the load on the roof and the load on the third floor.
そして、２階までの木造部の柱、壁及び床の荷重を、１階の区画毎に集計し、１階の鉄筋コンクリート造の部材にかかる荷重を算出し、１階部分の構造を評価する。この際、従来の計算のように、平均された荷重を利用しないため、正しい荷重条件で各部材に伝達される荷重を計算することができる。 Then, the loads on the pillars, walls and floors of the wooden part up to the second floor are tabulated for each section of the first floor, the loads applied to the members of the reinforced concrete structure on the first floor are calculated, and the structure of the first floor portion is evaluated. At this time, unlike the conventional calculation, since the average load is not used, the load transmitted to each member under the correct load condition can be calculated.
図２は、１階が鉄筋コンクリート造であり２階が木造である建築物の平面図であり、（ａ）は木造の２階の平面図、（ｂ）は鉄筋コンクリート造の１階の平面図、（ｃ）は（ａ）と（ｂ）を重ね合わせた図である。なお、この例では、木造の２階（ａ）と鉄筋コンクリート造の１階（ｂ）では間取りが異なる。 FIG. 2 is a plan view of a building in which the first floor is reinforced concrete and the second floor is wooden, (a) is a plan view of the second floor of the wooden structure, (b) is a plan view of the first floor of the reinforced concrete structure, (C) is the figure which superimposed (a) and (b). In this example, the floor plan is different between the wooden second floor (a) and the reinforced concrete first floor (b).
本実施形態に係る混構造計算システムでは、１階の各区画は、鉄筋コンクリート造である１階の壁によって囲まれた区画として定義されることが好ましい。
例えば、図２に示すように、柱１及び壁２で構成された木造の２階の間取り（図２（ａ））と、鉄筋コンクリート造の壁３で構成された１階の間取り（図２（ｂ））が異なる場合では、鉄筋コンクリート造の壁３で囲まれた領域が一区画として定義される。そして、この区画内に含まれる柱１、壁２並びに床の荷重が合計される。
In the mixed structure calculation system according to the present embodiment, each section on the first floor is preferably defined as a section surrounded by a wall on the first floor made of reinforced concrete.
For example, as shown in FIG. 2, the floor plan of the second floor (FIG. 2 (a)) composed of the pillar 1 and the wall 2 and the floor plan of the first floor composed of the reinforced concrete wall 3 (FIG. 2 ( When b)) is different, the area surrounded by the reinforced concrete wall 3 is defined as one section. And the load of the pillar 1, the wall 2, and floor contained in this division is totaled.
区画の境界としては、鉄筋コンクリート造の壁３の厚さ方向の中心を通る直線を採用してもよいし、規定される区画の内側あるいは外側の壁面を採用してもよい。
区画の境界として鉄筋コンクリート造の壁３の厚さ方向の中心を通る直線を採用した場合、隣り合う区画の境界線が木造階の柱１又は壁２を２分割するが、この場合には、これら柱１又は壁２の荷重を２分の１にすればよい。
As a partition boundary, a straight line passing through the center in the thickness direction of the reinforced concrete wall 3 may be used, or a wall surface inside or outside the defined partition may be used.
When a straight line passing through the center in the thickness direction of the reinforced concrete wall 3 is adopted as the boundary of the partition, the boundary line of the adjacent partition divides the pillar 1 or the wall 2 of the wooden floor into two parts. What is necessary is just to halve the load of the pillar 1 or the wall 2.
図３には、木造階である２階の床、柱及び壁の荷重が示されている。また、荷重計算の対象となる１階の区画Ｓ１が区画の境界線４によって示されている。一区画にかかる２階部分からの荷重は、例えば、図３に示すような荷重分布の場合には、次のように計算できる。なお、以下の計算に置いて、隣り合う区画の境界線上にある柱又は壁の荷重は２分の１としてある。 FIG. 3 shows loads of floors, columns, and walls on the second floor, which is a wooden floor. A section S1 on the first floor, which is a target of load calculation, is indicated by a boundary line 4 of the section. For example, in the case of a load distribution as shown in FIG. 3, the load from the second floor portion applied to one section can be calculated as follows. In addition, in the following calculation, the load of the pillar or wall on the boundary line of an adjacent division is set to 1/2.
床上荷重＝１４．０９＋１．６３＋１．６６
＝１７．３８（ｋＮ）
壁荷重＝（０．４８＋０．４８＋０．４８＋０．４８）
＋（０．４１＋０．４１＋０．２１＋０．４１＋０．４１＋０．４１＋０．４１＋０．２１＋０．４１＋０．４１）／２
＝１．９２＋１．８５
＝３．７７（ｋＮ）
柱荷重＝（２．３８＋０．８９）
＋（３．３９＋４．３＋５．７１＋５．５３＋４．３３＋３．３９＋４．３＋５．７１＋５．５３＋４．３３）／２
＝３．２７＋２３．２６
＝２６．５３（ｋＮ）
Floor load = 14.09 + 1.63 + 1.66
= 17.38 (kN)
Wall load = (0.48 + 0.48 + 0.48 + 0.48)
+ (0.41 + 0.41 + 0.21 + 0.41 + 0.41 + 0.41 + 0.41 + 0.21 + 0.41 + 0.41) / 2
= 1.92 + 1.85
= 3.77 (kN)
Column load = (2.38 + 0.89)
+ (3.39 + 4.3 + 5.71 + 5.53 + 4.33 + 3.39 + 4.3 + 5.71 + 5.53 + 4.33) / 2
= 3.27 + 23.26
= 26.53 (kN)
上記の床、柱及び壁の全荷重を合計すると、区画Ｓ１にかかる全荷重は４７．６８（ｋＮ）となる。
また、区画Ｓ１の面積は１．８２×４．０９５＝７．４５２９（ｍ２）となるので、接地圧は、４７．６８／７．４５２９＝６．４０（ｋＮ／ｍ２）と算出できる。
When the total loads of the floors, columns, and walls are added up, the total load applied to the section S1 is 47.68 (kN).
Further, since the area of the section S1 is 1.82 × 4.095 = 7.4529 (m 2 ), the contact pressure can be calculated as 47.68 / 7.4529 = 6.40 (kN / m 2 ). .
また、本実施形態に係る混構造計算システムでは、上記のように定義された各区画を、亀甲分割により複数の領域に分割することが好ましい。 In the mixed structure calculation system according to the present embodiment, it is preferable to divide each section defined as described above into a plurality of regions by turtle shell division.
ここで、亀甲分割とは、一つの区画を直線（図４の亀甲分割線５）によって分割することを意味する。例えば図４に示すように、亀甲分割線５は、区画の頂点から各境界線に対して４５°で延びる線と、この線の交点とを結ぶ線によって構成される。なお、区画が正方形の場合には、対角線が亀甲分割線となる。 Here, the turtle shell division means that one section is divided by a straight line (turtle shell dividing line 5 in FIG. 4). For example, as shown in FIG. 4, the turtle shell dividing line 5 is configured by a line connecting a line extending at 45 ° with respect to each boundary line from the top of the section and an intersection of the lines. In addition, when a division is a square, a diagonal is a turtle shell dividing line.
上記亀甲分割により、一つの区画は４つの領域に分割され、各領域に含まれる壁毎に分割された領域の荷重を負担するようになる。図４の例では、亀甲分割線Ｌ１、Ｌ２及び区画の一辺を構成する壁Ｗ１によって囲まれた領域の荷重は壁Ｗ１が負担する。 By the turtle shell division, one section is divided into four regions, and bears the load of the region divided for each wall included in each region. In the example of FIG. 4, the wall W1 bears the load in the region surrounded by the turtle shell dividing lines L1 and L2 and the wall W1 constituting one side of the partition.
なお、くびれを有する多角形や、矩形であっても壁の一部が無い場合は、区画内の総荷重を、区画を構成する辺の長さで按分して荷重を設定する。 In addition, when there is no part of the wall even if it is a polygon having a constriction or a rectangle, the load is set by dividing the total load in the compartment by the length of the side constituting the compartment.
例えば、区画の総荷重が２２ｋＮ、１辺が３ｍの正方形の区画で、ある１辺が１ｍ壁が無い箇所があり、辺を構成する壁の水平方向の長さが２ｍしかない場合、壁の単位長さ当たりの荷重は２２／１１＝２ｋＮ／ｍである。そして、水平方向の長さが３ｍである壁には６ｋＮ、水平方向の長さが２ｍである壁には４ｋＮの荷重がかかるものとして按分する。 For example, if a section is a square section with a total load of 22kN, one side of 3m, and one side has no 1m wall, and the horizontal length of the wall constituting the side is only 2m, The load per unit length is 22/11 = 2 kN / m. Then, it is prorated that a load of 6 kN is applied to a wall having a horizontal length of 3 m and a load of 4 kN is applied to a wall having a horizontal length of 2 m.
次いで、区画の一辺を構成する壁について荷重を計算する。このとき、壁に構成される開口部（窓やドアなど）を考慮してフレーム計算のためにモデル化を行い、壁の構成部材を壁梁と柱に分割する。 Then, a load is calculated about the wall which comprises one side of a division. At this time, modeling for frame calculation is performed in consideration of openings (windows, doors, etc.) formed in the wall, and the constituent members of the wall are divided into wall beams and columns.
図５は鉄筋コンクリート造階の平面図の一例であり、壁や小梁を通る芯を互いに直交するＸ通り・Ｙ通りとしている。図６は図５のＸ０通りにおける立面図である。
図６に示すような開口部６を有する壁は、開口部６がない箇所は壁柱７、開口部６がある箇所は壁梁８としてモデル化される。
FIG. 5 is an example of a plan view of a reinforced concrete floor, and the cores passing through walls and small beams are set to X and Y ways orthogonal to each other. FIG. 6 is an elevational view along X0 of FIG.
The wall having the opening 6 as shown in FIG. 6 is modeled as a wall column 7 where there is no opening 6 and a wall beam 8 where there is an opening 6.
次いで、上記のモデル化されたフレーム（骨組み）で応力計算を行う。そして、応力計算の結果と鉄筋コンクリート断面の許容値から、壁柱及び壁梁の許容応力度判定を行う。 Next, a stress calculation is performed on the modeled frame (frame). Then, the allowable stress degree of the wall column and the wall beam is determined from the result of the stress calculation and the allowable value of the reinforced concrete cross section.
また、１階の鉄筋コンクリート造階の天井部に設けられたコンクリート造のスラブの荷重は、スラブの全自重を、亀甲分割によって分割された面積で按分してそれぞれの壁に分配する。 Moreover, the load of the concrete slab provided in the ceiling part of the reinforced concrete floor on the first floor distributes the total weight of the slab to each wall by dividing it by the area divided by the turtle shell division.
出力の結果としては、特に限定されないが、荷重・外力計算（荷重表：２階床、壁、梁、特殊荷重の集計）、耐力壁の検討（基準法施行令に沿った壁の検討）、偏心率の算定、ねじれ補正係数（基準法施行令に沿った建物のバランスの検討）、フレーム応力（ＲＣ部材をモデル化した、フレーム応力計算）、断面算定（フレーム応力計算とＲＣ断面性能より許容応力度判定）といった、構造計算書に利用することができる項目が出力されることが好ましい。 As a result of output, although not particularly limited, load / external force calculation (load table: total of 2nd floor, walls, beams, special loads), examination of bearing walls (examination of walls in accordance with the Enforcement Ordinance of the Standard Act), Eccentricity calculation, torsion correction factor (examination of building balance in accordance with the Ordinance for Enforcement of Standard Law), frame stress (frame stress calculation modeling RC members), cross-section calculation (allowable from frame stress calculation and RC cross-section performance) It is preferable to output items that can be used in the structural calculation sheet, such as stress level determination.
上記混構造計算方法は、例えば、１階が鉄筋コンクリート造であり、２階及び３階が木造である混構造の建築物の構造計算を行うプログラムであって、建築物の設計データに基づいて、建築物の屋根の荷重で３階部分の構造を評価するステップと、屋根の荷重及び３階の荷重で２階部分の構造を評価するステップと、２階までの木造部の柱、壁及び床の荷重を１階の区画毎に集計し、１階の鉄筋コンクリート造の部材にかかる荷重を算出するステップと、１階部分の構造を評価するステップとを含む混構造計算プログラムとして、記憶媒体に格納されて提供される。このようなソフトウェアが提供されることにより、従来、別個に計算されて、多大な労力を要していた混構造建築物の構造計算を容易に行うことができる。 The mixed structure calculation method is, for example, a program for calculating a structure of a mixed structure in which the first floor is reinforced concrete and the second and third floors are wooden, and based on the design data of the building, A step of evaluating the structure of the third floor part by the load of the roof of the building, a step of evaluating the structure of the second floor part by the load of the roof and the load of the third floor, and pillars, walls and floors of the wooden part up to the second floor Is stored in a storage medium as a mixed structure calculation program including a step of calculating a load applied to a reinforced concrete member on the first floor and a step of evaluating a structure of the first floor portion. To be provided. By providing such software, it is possible to easily calculate the structure of a mixed structure building that has been separately calculated and requires a lot of labor.
上記実施形態に係る混構造計算方法がプログラムとして提供される場合、例えば、ＰＣ（パーソナルコンピューター）やサーバー内での稼働が想定される。この場合、該プログラムの利用者は、ＰＣの表示装置等に表示される入力画面において必要な数値データや建築物の構成等の情報を入力する。 When the mixed structure calculation method according to the embodiment is provided as a program, for example, operation in a PC (personal computer) or a server is assumed. In this case, the user of the program inputs necessary numerical data and information such as the structure of the building on the input screen displayed on the display device of the PC.
例えば、建築物の間取り等の構成を視認する際に、通り芯毎の立面図の表示に切り替えるためのツールボタンが表示されてもよい。このような立面図を容易に表示できることにより、間口の入力を立面図から行うことができる。 For example, when visually recognizing a configuration such as a floor plan of a building, a tool button for switching to an elevation view display for each core may be displayed. Since such an elevation can be easily displayed, the frontage can be input from the elevation.
なお、鉄筋コンクリート造りに別途必要な立面計算を、鉄筋コンクリート造り用平面骨組計算システムであるフレミング（富士通エフ・アイ・ピー株式会社製）等の部品を取り込むことにより格段に効率化を図ることができる。 In addition, it is possible to remarkably improve the elevation calculation required separately for reinforced concrete construction by incorporating parts such as Fleming (manufactured by Fujitsu FIP Co., Ltd.), which is a plane framework calculation system for reinforced concrete construction. .
また、本発明によれば、１階が鉄筋コンクリート壁式構造であり、２階及び３階が木造である混構造の建築物の構造計算を行うシステムが提供される。
該システムは、建築物の設計データに基づいて、建築物の屋根の荷重で３階部分の構造を評価し、屋根の荷重及び３階の荷重で２階部分の構造を評価する木造階評価手段と、２階までの木造部の柱、壁及び床の荷重を１階の区画毎に集計し、１階の鉄筋コンクリート造の部材にかかる荷重を算出する荷重算出手段と、１階部分の構造を評価するコンクリート造階評価手段と、を含むことを特徴とする。なお、上記システムの各構成は、前述の混構造計算方法と同様であるため説明を省略する。
Moreover, according to this invention, the system which performs the structural calculation of the building of the mixed structure whose 1st floor is a reinforced concrete wall type structure and 2nd and 3rd floors are wooden is provided.
The system evaluates the structure of the third floor portion by the load of the building roof based on the design data of the building, and evaluates the structure of the second floor portion by the load of the roof and the load of the third floor. And the load calculation means for calculating the load on the reinforced concrete structure on the first floor by summing up the loads of the pillars, walls and floors of the wooden part up to the second floor for each section of the first floor, and the structure of the first floor part And a concrete floor evaluation means for evaluation. Note that each configuration of the system is the same as that of the above-described mixed structure calculation method, and a description thereof will be omitted.
上記混構造計算システムを実現するために、荷重の計算、按分計算等の演算を行うための演算装置（ＣＰＵ等）、情報を入力のための入力装置（キーボード、マウス等）、表示装置（電子ディスプレイ等）、記憶装置（ハードディスク、ＲＡＭ、ＲＯＭ、）等から構成されてもよい。 In order to realize the above mixed structure calculation system, an arithmetic device (CPU, etc.) for performing calculations such as load calculation and proportional calculation, an input device (keyboard, mouse, etc.) for inputting information, a display device (electronic Display, etc.), storage device (hard disk, RAM, ROM, etc.).
本発明に係る混構造計算システムでは、従来別個に行っていた木造階とコンクリート造階の計算を同一のシステム内で処理をすることが可能であるため、例えば、記憶装置において、木造階の荷重の情報を格納し、下階であるコンクリート造階の計算に直接利用することができる。これにより、従来の計算方法よりも、より正確な荷重の条件を適用させることが可能となる。 In the mixed structure calculation system according to the present invention, since it is possible to process the wooden floor and the concrete floor that have been separately performed in the same system, for example, in the storage device, the load on the wooden floor Can be stored and used directly in the calculation of the concrete floor, which is the lower floor. This makes it possible to apply a more accurate load condition than the conventional calculation method.
また、構造計算書や構造計算概要書等は、印刷装置から出力されてもよい。 Further, the structural calculation document, the structural calculation summary document, and the like may be output from the printing apparatus.
