Abstract
This paper is concerned with stability problems of spatial trusses due to thermal and mechanical loading. A fully coupled thermomechanical truss element is formulated which accounts also for the temperature dependence of the constitutive parameters. The formulation leads to a non‐linear problem which is solved by the finite element method. The computation of critical points is based on the linearization of the coupled weak form which yields a non‐symmetric tangent operator. The formulation and its associated algorithmic treatment is validated by means of examples.
