      <abstract xml:lang="ru">
        <p>Кольцевая и арочная крепь, подвергающаяся действию нагрузок, может разрушиться либо от недостаточной прочности, либо от недостаточной устойчивости, которая проверяется определением критической нагрузки, вызываю­щей потерю устойчивости данной конструкции.</p>

        <p>Ring and arch supports subjected to loads may fail either from insufficient strength or from insufficient stability, which is verified by determining the critical load causing loss of stability of the structure.</p>
