heal.abstract	In this paper, the effect of geometrical imperfections due to joint angle deviations of a simple rectangular frame is thoroughly discussed. It has been found that the deviation from the right angle of the joint with respect to the center-lines of the two members of the frame affects significantly the buckling strength of the frame. It is also shown that such geometrical imperfections do not always decrease the strength of such structures but sometimes, even though loading imperfections exist, they act on the favorable side regarding its strength. The influence of various geometric parameters such as slenderness ratio as well as length and moment of inertia ratio of the members on the critical load of the imperfect frame is thoroughly discussed and representative case studies are presented. © Springer-Verlag 2009.	en
