      <abstract xml:lang="ru">
        <p>Четырехшарнирная крепь представляет собой статически определимую геометрически изменяемую систему с одной степенью свободы. В наземных конструкциях геометрически изменяемые системы почти не применяются ввиду их неустойчивости. Поэтому конкретной методики их расчета строительная механика не дает.</p>

      <abstract xml:lang="en">
        <p>A four-hinged brace is a statically defined geometrically variable system with one degree of freedom. In ground structures, geometrically variable systems are almost never used due to their instability. Therefore, the construction mechanics does not provide a specific methodology for their calculation.</p>
