面内曲げモーメントを受ける正方形板の後座屈挙動

Post Buckling Behavior of a Square Plate Subjected to Bending Stresses Applied in the Plane of Plate 浜田 敬之介(Keinosuke Hamada) 要旨 : 高張力鋼の進歩によって鋼構造は経済的に設計されることが可能になり,これは軽量化,薄 肉化につながることになった。しかし,プレートガーダーの腹板の設計基準は線型理論によ る座屈荷重によっている。設計基準が座屈荷重によるかぎり高張力鋼を使用することが普 通鋼に比べて有利であるとはいえない。しかし,大変形理論によって後座屈域における耐荷 力を考慮することによって高張力鋼の有利性が可能になる。ここでは面内曲げモーメント を受ける正方形板の後座屈域における挙動をカルマンの方程式を解いて解析し,実験値と 比較した。この結果,高張力鋼を腹板として使用する有利性があきらかになった。 Synopsis :

Owing to improvement of hightension steel, it has become possible to economically design steel structure, that is, to make it thinner and lighter. In spite of this, in the design of webplates of plate girders, buckling load derived from the linear theory is used as criterion. As long as the criterion is based on buckling load, hightension steel is not always more advantageous than carbon steel in the design for the webplates. However, by considering strength of steel in post-buckled range with the aid of large deflection theory, it is possible to make a good use of properties of high tension steel. In this paper, post buckling behavior of a square plate subjected to bending stress is analyzed by solving von Karman's large deflection equation and these results are compared with experimental results. In conclusion, it has become apparent that the use of hightension steel for webplates is more advantageous than carbon steel.
