Abstract | Full Text
They cause mistakes in the transfer of forces in specific points and invariability of sizes and types of cross sections of rods in the course of their deformation. The approach to the analysis of rectangular section columns is proposed. The new approach originates from the three-dimensional theory supplemented by the superelement technology. The column is divided into sections and finite elements. The analysis of physically nonlinear structures is executed using the PRINS software. The flow theory is used to identify the characteristics of finite elements. Huber-Mises plasticity criterion is applied. The console beam loaded by concentrated forces on the free end is calculated to verify the element. The limiting load value identified by PRINS software complies with the theoretical values derived using the theory of limit equilibrium.<br>Разработанный авторами на основе трехмерной теории упругости суперэлемент колонны прямоугольного сечения, предназначенный для линейных расчетов, развит применительно к расчету подобных колонн с учетом пластических деформаций. Элемент адаптирован к вычислительному комплексу ПРИНС и в составе этого комплекса может использоваться для физически нелинейного расчета строительных сооружений, содержащих колонны прямоугольного сечения.
