The computation of the continuation is known to be diﬃcult due to special properties of the stiﬀness matrices of structures in the vicinity of singular points. A new expansion method is presented that leads to a robust and accurate continuation algorithm. The method is applied to the stability analysis of a spherical dome for symmetric and asymmetric snow loads.</abstract><trans-abstract xml:lang="ru">В работе излагается новый метод вычисления продолжения решения в сингулярных точках, основанный на расширении системы разрешающих уранений и обладающий хорошей сходимостью и точностью.
