The present research is devoted to study of a lateral buckling of truss with linear elastic side supports. The elastic support reaction in relation to force in compressed chord and coefficient of buckling length related to side support distance are also calculated. The effect of slope of side support on limit force is also considered. The nonlinear analysis of two roof trusses are carried out. The results are compared to design code requirements [1]. The design sensitivity analysis of limit load due to side support stiffness is carried out. A sensitivity of limit load due to side support localization is calculated. The influence line of the variation of the limit load of the truss due to introducing side supports of unit stiffness in chord joints is found. It has been found that for some side support localization adding new side support may cause decrease of limit load.
