“…The stability problem in beam elements is well recognized and described, e.g. in [7].The relationship between the critical moment Mcr of the bending I-beam and the critical force Ncr of the compression chord was presented in the paper [8]. The literature also includes information on equivalent truss models in the analysis of bending I-beams [9].…”

The article presents graphical methods for determine critical loads of column and beam elements based on experimental results. The author presents the principles of using each method and the results of author's experimental tests on the instability phenomenon of planar steel truss with imperfections. The discussed methods were used to determine critical load of the tested truss, next compared with the results of numerical analysis. The validity of methods for determining the critical moment in the truss analysis has been confirmed.
