Abstract

The article considers the problem of stability of the thin-walled supported cylindrical elements under loading with quickly increasing external pressure.
The problem is solved in a linear formulation. The discreteness of the location of the ribs and their asymmetrical location relative
to the middle surface of the shell is taken into account. The equation of motion of system is received with with the use of Lagranzhe equation of the
second sort with single-term approximation of movings. To define critical loadings the criterium corresponding to the beginning of the intensive development
of deflections is used.
