This paper focuses on the research of the stress mechanism of the ribbed shell structure in statics, dynamics and under the explosive load on the basis of the engineering practice of cave depot of single aircraft. in this paper, according to the classical shell theories, the basic differential equilibrium of the ribbed shell structure and the finite element analysis of 3d rippled plate are established, in which the function of annular ribs reinforcement bars and 3d ripped steel plates are distributed in the range of the steel, and the functions along the longitude direction of tension, bending, and torsion are neglected ; applied with dynamic analytical theory, the dynamic model of ribbed shell structure and the analytical theory model of elastic - plastic are set up ; the triangle series method is used to solve the displacement and stress under the distributed load and the concentrated load of the ribbed shell structure
本文以軍用機場地面單機掩蔽庫工程建設為工程背景，首次對內襯三維波紋鋼板混凝土拱型復合結構的受力機理進行了靜力、動力和爆炸荷載的分析研究。根據將橫肋、鋼筋及三維波紋鋼板的作用均勻分佈在殼體范圍內的情況，忽略橫肋、鋼筋及三維波紋鋼板沿殼體母線方向的抗拉、抗彎及其抗扭作用，首次推導出了內襯三維波紋鋼板混凝土殼體的微分平衡方程，建立了有限元計算模型，並採用三角函數法，求解了三維波紋鋼板混凝土拱型復合結構在分佈荷載和集中荷載作用下的位移響應和應力響應，並與普通殼體進行了比較。 -
