Etude du poids et de la raideur des treillis Warren, Pratt et Howe
This study compares the self weight and the rigidity of classical trusses as Warren, Pratt or Howe trusses, subjected to fixed or stochastic loads. The comparison is done by the use of a new approach based on morphological indicators. Those dimensionless numbers allow to reduce the amount of parameters in the process of optimisation (or conception) and to produce universal curves related to a family of trusses. Those efficiency curves allow to design trusses, but also to optimise their weight or their stiffness, irrespective of the material, de type of sections, the span or the value of the loads.
