ABSTRACT
The paper presents the stability issue of unbraced steel frames with special attention paid to the problem of determining the value of critical load in these frames.
The paper discusses ways of critical load determination in frames with the use of selected methods of stability analysis. The presented analysis procedures were used in calculations of certain steel frames.
The issue presented in the paper is important from the practical point of view, and therefore, it should be taken into account in the design process of such frames.
