Prager-structures differ from classical least-weight trusses (or Michell continua) in two respects: the sign of all member forces must be the same and the vertical location of all external loads is to be optimized. A systematic method for constructing plane Prager-structures for any system of vertical loads is outlined and illustrated with examples. It is established that plane Prager-structures (a) always consist of a single funicular and (b) the optimal elevation of the loads also provides an influence line for the minimum weight.
