Abstract
This paper presents a numerical stability analysis of grillage structures. The analysis is based on finite element methods. The linearized equilibrium equations are derived by applying the linearized virtual work principle and the non-linear cross-sectional displacement field. Material is assumed to be homogeneous, isotropic and linearly elastic. Stability analysis is treated as a matrix eigenvalue problem (linear stability). Analytical and numerical results are compared for pinned rectangular grillage structures subjected to concentrated forces.
