On the contrary a sufficiently approximated evaluation of equilibrium paths of imperfect structures can be easily obtained in the asymptotic Koiter's approach, looking again for the solution of the equilibrium problem (\ref{PS2}) of the imperfect structure in the same bifurcation manifold (\ref{PS7}) of the perfect one. In this approach the presence of imperfections simply redefines the final ($\lambda,\xi_1,\ldots,\xi_m$) relationships by adding the coefficients
