The objective of this study is to investigate the accuracy and computational efficiency of two formulations for performing the geometrically nonlinear thermal analysis of plane framed structures. The formulations considered are the followings: the Beam-Column formulation and the updated Lagrangian version of the finite element formulation. The Beam-Column method is based on an Eulerian formulation that incorporates effects of large joint displacements. Local member force-deformation relationships are based on the Beam-Column approach that includes the axial strain, flexural bowing, and thermal...
