WOODEN STRUCTURE LOAD BEARING WALL
To provide a gypsum-based bearing face material that increases a wall magnification of a wooden structure load bearing wall without additionally attaching a reinforcing material or stiffening material and also without increasing a specific gravity and/or thickness of a gypsum-based face material.SOLUTION: A gypsum-based bearing face material 10 for a wooden structure load bearing wall is configured from a main material or core material formed from a plate-shaped gypsum-based hardening body in which an inorganic fiber and an organic-based strength enhancing material are blended so that nail-side resistance of 500 N or more is exhibited, and a paper member that covers at least front and rear surfaces of the main material or core material. This bearing face material has surface density within a range of 6.5-8.9 kg/m2 and a compression strength of 6.5 N/mm2 or more, exhibits ultimate displacement (δu) that is greater than 20×10-3 rad and initial stiffness (K) that is 2.0 kN/10-3 rad or more in an in-plane shear test of the load bearing wall, and increases a ductility factor (μ) not only by an increase in the ultimate displacement, but also a decrease in yielding point displacement (δv), thereby effectively or efficiently increasing a wall magnification and short-term standard shear strength (P0) of the wooden structure load bearing wall.SELECTED DRAWING: Figure 2
【課題】補強材又は補剛材を付加的に取付けることなく、石膏系面材の比重及び／又は板厚を増大することもなく、木構造耐力壁の壁倍率を増大する。【解決手段】木構造耐力壁用の石膏系耐力面材１０は、５００Ｎ以上のくぎ側面抵抗を発揮するように無機質繊維及び有機系強度向上材を配合した板状の石膏硬化体からなる主材又は芯材と、主材又は芯材の少なくとも表裏面を被覆する紙部材とから構成される。この耐力面材は、６.５～８．９kg/m2の範囲内の面密度および６．５N/mm2以上の圧縮強度を有し、耐力壁の面内せん断試験において、２０×１０-3radよりも大きい終局変位（δu)および２．０ｋＮ／１０-3rad以上の初期剛性（K)を発揮し、終局変位の増大だけでなく、降伏点変位(δv)の低減によっても塑性率(μ)を増大し、これにより、木構造耐力壁の壁倍率及び短期基準せん断耐力(P0)を効果的又は効率的に増大する。【選択図】図２
