Abstract

The adequacy of a structure in strength, stiffness and stability can be evaluated using morphological indicators. This article establishes these indicators for volume, displacement and buckling, for roof trusses. Easy to use graphs then allow to take design decisions at the early stage of conceptual design. Although less precise than computer driven optimization methods, morphological indicators are a simple tool to choose an appropriate typology. In this article roof trusses are added to the morphological indicator theory.
