ての上階床や屋根もしくは小屋梁が耐力壁に有効に伝達
し、該耐力壁が抵抗することにより対処している。Therefore, structurally, for example, in response to wind pressure as a horizontal force, the out-of-plane bending force applied to the outer wall and roof is effectively transmitted to the load-bearing wall by the upper floor, roof, or roof beam as a horizontal structural surface. The load-bearing wall copes with this by resisting.
よって、前記水平構面は水平力を有効に伝達するために
所定の面内剛性を有するものとする必要がある。Therefore, the horizontal structural surface needs to have a predetermined in-plane rigidity in order to effectively transmit the horizontal force.
しかしながら、かかる木質構造建築物における床体は、

題があった。However, the flooring of such wooden structure buildings is
In order to achieve the specified in-plane rigidity, considerable care is required in terms of structural design and construction. For example, when joining floor joists and floor joists, a specified number or more of them must be used to integrate the two. There was a problem in that the work was complicated because it required nail driving work, etc.
また、かかる木質構造建築物を共同住宅として利用する
ような場合には、界床としての２階床は防火性能や遮音
性能で必ずしも充分ではないという問題も有していた。In addition, when such a wooden structure building is used as a condominium, there is a problem in that the second floor, which serves as a boundary floor, does not necessarily have sufficient fire prevention and sound insulation performance.
