Summary

 
In the article of the developed analytical models for the study of the stress-strain State of reinforce toroidal frames adjustable rigidity orthotropic shells and analytical dependences do without their carrying capacity. Found that with increasing pressure component of axial bending stresses inside the cavity in the section kills have increased. With the increase in the relative lengths of the degree of influence over am is essential, and hoop stresses is reduced across the length of an am space and can change sign, becoming stretching. The degree of in-fluence of flexural component of axial stresses a more substantial for the short shells. Installation of toroidal frames, more pliable than traditional frames brand profile allows by increasing pressure to achieve the desired stiffness intracavitary, improve competitiveness and assist carrier reduction to 20 % by weight of deep Corps of objects for different purposes.
