本研究では，面外方向に対する面内方向の回転剛性の比率および矩形断面の強軸に対する弱軸の断面二次モーメント比率が木鋼シェルの座屈荷重に与える影響を連続体理論および数値解析を応用して検討し，両者を考慮した木鋼シェルの弾性座屈荷重の評価手法の提案を試みました。主に座屈解析の方で貢献した研究です。理論解と数値解両方から回帰式を作ったり滅多矢鱈な部分が多く，当時はなんでもやればいいものではない，ということを何度も説き続けましたが分かってもらえませんでした。論文はこちら
The authors have proposed effective steel connections achieving high bending stiffness and strength for timber grid-shell structures, and confirmed their performances through real size mock-up tests. In this research, reflecting the test results, the buckling strength of 24m-span timber grid-shell with and without diagonal bracing roofs are discussed. Their theoretical buckling strength including the rotational stiffness at connections are derived using continuum shell analogy, and compared with the results of discrete FEM analyses. Finally, the reduction factor equations of buckling strength as the functions of in-plane / out-of-plane bending stiffness ratio and two directional rotational stiffness are proposed, followed by confirming their validity.
