Finite element model for initial stability analysis of semi-rigid frames

The paper presents a numerical stability analysis of semi-rigid frames using finite element model. Two node beam element is applied and semi-rigid connections are described by the initial connection stiffness. Stability problems are treated as a matrix eigenvalue problem, i.e. an initial stability analysis is performed. Material is assumed to be linear elastic.
