The request for sustainable structures has encouraged the development of structural optimization methods aimed to design efficient structures and to minimize the use of construction materials. Funicular structures are an example of optimized structural systems, being able to bear the design load without exploiting bending moments. Here, we have used the eccentricity measure to study and quantify the funicular behaviour of 1D and 2D structures. Then, we have formulated an optimization process where the structures’ shape is updated in order to make them as much as possible funicular in a relaxed form. We have carried out numerical experiments to test the algorithm, the early results shown an improvement of the structural efficiency.

Abstract
The request for sustainable structures has encouraged the development of structural optimization methods aimed to design efficient structures and to minimize the use of construction materials. Funicular structures are an example of optimized structural systems, being able to bear the design load without exploiting bending moments. Here, we have used the eccentricity measure to study and quantify the funicular behaviour of 1D and 2D structures. Then, we have formulated an optimization process where the structures’ shape is updated in order to make them as much as possible funicular in a relaxed form. We have carried out numerical experiments to test the algorithm, the early results shown an improvement of the structural efficiency.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
