Abstract: The paper presents the analysis and optimization of the geometric parameters of I-profile of the main girder of the single-beam bridge crane. The reduction of the cross sectional area of the welded I-girder is set as the objective function. The criteria of permissible stresses in the characteristic points of I-section, stability of the upper plate of I-profile, permissible static deflection of the girder, minimum plate thicknesses and some geometric limits, were applied as the constraint functions for this optimization problem. The obtained results of optimization were verified on examples of implemented solutions of the single-beam bridge cranes, showing how much the mass can be saved in application of the welded I-profiles in comparison to standard rolled I-profiles, which are most commonly applied.
