Abstract
The main aim of this paper is to extend the recently developed methods for calculating the
buckling loads of planar symmetric frames to include the effect of semi-rigidity of the joints. This is
achieved by decomposing a symmetric model into two submodels and then healing them in such a
manner that the :::union::: of the eigenvalues of the healed submodels result in the eigenvalues of the
entire model. Thus the critical load of the frame is obtained using the eigenvalues of its submodels.
