The present research is devoted to the study of out-of-plane buckling of trusses with elastic side bracing. Inthis paper, a sensitivity analysis of critical buckling loads of a truss due to bracing stiffness is carried out. A method based on the sensitivity analysis for the determination of the threshold bracing stiffness conditionfor full bracing of a truss is proposed. The influence lines of the unit change of the bracing stiffness onthe buckling load, for different initial bracing stiffness, are investigated. The approximations of an exactrelation between the buckling load and bracing stiffness are found. The buckling length related to theside-support distance as a function of bracing stiffness is also determined. It is shown that the bucklinglength of truss chords with elastic side supports is larger than that assumed in design codes.
