Steel trusses have a much greater strength and stiffness in their plane than out of their plane, and therefore should be braced against lateral deflection and twisting. Such elements like purlins apart from bearing vertical load are part of bracing that stabilize roof trusses against distortional buckling. The stability of trusses with elastic bracing was investigated in an experimental research. Braces situated at some angle measured from the horizontal line not only prevent the out-of-plane buckling of the main structural elements, but also relieves the main bearing member and becomes overloaded itself . Since the problems of sloping bracing are likely to occur in different roof structures it is important to study it in view of the stability of the main structural elements. The present research is devoted to study lateral buckling of truss with sloping linear elastic side supports. The research is focused on the determination of the relation between the limit and the buckling load of trusses due to the bracing stiffness and angle.
