Abstract
This paper refers to a qualitative investigation of the performance of structural membranes in the field of lightweight structures, aiming to understand the strategies used by architects and engineers to achieve optimum performance of these structures. This investigation is based on the analysis of existing buildings using membranes and cable net roofs, grid shells and wooden shells covered by glass and membrane, as well as steel supporting systems covered by translucent tiles. It was observed that the optimum performance of lightweight structures is related to the spatial stability of the whole structure, to the use of high strength of materials and to the low density of the structure. The strategies are based on the relation among the form of components, the three-dimensional arrangement of the whole structure and the flow of forces, aiming the best force path and the best use of materials.
