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
