【発明の詳細な説明】
〔産業上の利用分野］
この発明は主として建築物等、鉄筋コンクリート構造の
構築物の骨組をなす架構構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention mainly relates to a frame structure forming the frame of a reinforced concrete structure such as a building.
〔従来技術とこの発明の解決しようとする課題〕一般に
鉄筋コンクリート構造物では所定の荷重を越えて降伏点
に達した骨組は崩壊に至る。[Prior Art and Problems to be Solved by the Present Invention] In general, in reinforced concrete structures, a frame that exceeds a predetermined load and reaches a yield point will collapse.
そこで骨組内に配した筋違、壁等の変形能を向上して降
伏点を越しても骨組が直ちに崩壊に至らない構造、すな
わち靭性のある骨組の開発が要望されている。Therefore, there is a need to develop a structure that improves the deformability of the braces, walls, etc. arranged within the frame so that the frame does not collapse immediately even if the yield point is exceeded, that is, a frame with toughness.
この発明も前記要望に対処すべく開発したもので、鉄骨

ある。This invention was also developed in response to the above-mentioned need, and because steel structures have greater toughness than reinforced concrete,
The purpose of this method was to improve the toughness of the frame of a reinforced concrete structure by replacing the yielding part of the frame with a steel frame structure.
この発明は鉄筋コンクリート構造の柱、梁等からなる骨

In a frame consisting of beams 2, the yielding parts at the center or both end hinges are made of steel structure 3 or steel reinforced concrete structure, and the toughness at the time of frame collapse is improved by deforming the steel section 3. be. According to this framework, as shown in Fig. 2, the steel frame section S or the steel reinforced concrete section SRC can be expected to deform even under a load that would cause the frame RC of a reinforced concrete structure or the frame mPc of a prestressed structure to collapse, and therefore the toughness of the frame is will improve.
