- ItemFlexural-torsional buckling of single, eccentrically loaded, unequal-legged angle struts(Stellenbosch : Stellenbosch University, 1994) Bastiaanse, Gerrit; Dunaiski, P. E.; Stellenbosch University. Faculty of Engineering. Dept. of Mechanical and Mechatronic Engineering.ENGLISH ABSTRACT: Unequal-legged angles are used most commonly as truss elements or as lateral bracing for elements of steel structures. In most of these applications, the angles are connected to gusset plates through two or more bolts, or the equivalent in welding. These angles are loaded eccentrically with respect to their cross-sectional centroid. Although angle struts are loaded eccentrically in most application, no specific design method exists for the design of eccentrically loaded angle struts. The design curves provided in SABS 0162-1:1993 are only valid for concentrically loaded sections with a symmetrical cross-section. The user is warned only against the effect of flexuraltorsional buckling on the ultimate capacity. The beam-column theory can be used for the design of eccentrically loaded, unequal-legged angle struts. However, the formulas available to determine the ultimate flexural capacity of unequal-legged angle struts are complex and not easily accessible. It was decided therefore to develop a design method, based on the method in SABS 0162-1:1993, which could be used specificially for the design of eccentrically loaded truss compression members.
