Abstract

The POST-BUCKLING BEHAVIOR of rectangular frames in elastic domain is studied in depth. In analysis, unsymmetrical geometry, sway possibility and support conditions are considered in order to find their influences on load- deflection path and non-linear deformations. The static PERTURBATION TECHNIQUE is used for analysis and discussion. The first, second and third order perturbation problem, as an accuracy measurement, for the frame are solved and the solutions are compared with previously published papers. The results reveal that the symmetric frame with sway movement, due to non-axial force in beam, has symmetric BIFURCATION point in the first order perturbation analysis. However, the POST-BUCKLING BEHAVIOR of un-symmetric frames with or without sway is bifurcated in an asymmetric manner.
