Jednowymiarowy ciągły model stateczności sprężystej siatkowych dźwigarów powierzchniowych

The paper deals with linear equations of stability for a one-dimensional continuous model of elastic surface structures with a dense regular lattice of elements. The equations were obtained by applying Woźniak's concept of continuum mechanics with internal constraints to equations of stability of Cosserats' surface, being two-dimensional continuous model for surface grids and perforated shells. The condition of stability in the Euler sense was formulated, i.e. the adequate one-dimensional boundary – value problem was presented.
