EVALUATING METHOD OF OUT-OF-PLANE BUCKLING STRENGTH OF LATTICE-LIKE WALL

To establish an evaluating method of a strength of a lattice-like wall with respect to buckling in the out-of-plane direction.SOLUTION: Assuming that a diagonal member 22 between grid intersections of a lattice-like wall 20 is formed by connecting a partition plate 27a of a block 27 and an adhesive layer 28 in series, a Young's modulus Ege and a shearing elastic modulus Gge of the diagonal member 22 are calculated. Assuming that the lattice-like wall 20 is replaced with a brace model 120, the brace model 120 is replaced with a plate-like wall model 220, and rigidities of the lattice-like wall 20, the brace model 120, and the plate-like wall model 220 are equivalent to each other, a thickness Tge of the plate-like wall model 220 is calculated. Using an evaluation formula for an out-of-plane buckling strength of the lattice-like wall 20 obtained from an evaluation formula for an out-of-plane buckling strength of the plate-like wall model 220, a buckling start load Qboe or a maximum withstand load Qboeu of the lattice-like wall 20 is calculated.SELECTED DRAWING: Figure 10 【課題】面外方向の座屈に関する格子状壁の強度評価方法を確立する。【解決手段】格子状壁２０の格子の交点間の斜め材２２が、ブロック２７の仕切り板２７ａと接着剤２８の層が直列接続されてなるものとして、斜め材２２のヤング係数Ｅｇｅ及びせん断弾性係数Ｇｇｅを算出する。格子状壁２０がブレースモデル１２０に置換されて、ブレースモデル１２０が板状壁モデル２２０に置換されて、格子状壁２０、ブレースモデル１２０及び板状壁モデル２２０の剛性が互いに等価であるものとして、板状壁モデル２２０の厚さＴｇｅを算出する。板状壁モデル２２０の面外座屈強度の評価式から得られる格子状壁２０の面外座屈強度の評価式を用いて、格子状壁２０の座屈開始荷重Ｑｂｏｅ又は最大耐荷重Ｑｂｏｅｕを算出する。【選択図】図１０
