Post-Buckling Strength of Redundant Trusses
The load-carrying capacity of redundant rigid-jointed trusses after the trusses have buckled in their own plane is investigated. It is shown that (unlike similar statically determinate frameworks) such trusses buckle under increasing external forces, which generally approach limiting values as buckling progresses. The computation of the ultimate load is facilitated by the use of two theorems establishing upper and lower limits of the ultimate loads. Thus, the carrying capacity of the truss can be estimated by “surrounding” the unknown load between two easily calculable values. Of these limits, the lower bound can be computed to any desired accuracy.
