Abstract

Angle bars in compression are quite common in building and transport structures. However, the peculiarities of their behavior during the loss of stability and in supercritical equilibrium have not been sufficiently studied even within the limits of elastic deformations. The paper shows solutions for the stability of symmetric and asymmetric rods with an angle profile. The development of post-critical deformations is shown. The features of the behavior of the rods, obeying the hypotheses of V.Z. Vlasov.
