Course Description: The course aims to offer an analysis of the most important realizations, in the field of space structures, large span roofs and shells, regarding, at the same time, the buildings of the 50-70s, and with respect to nowadays architectures. Through a detailed analysis of the modeling and verification methods, the course purposes to explain, the different approaches, progressively proposed, for the calculation of shell and spatial structures. With this motivation, the form-finding and the successive validation phase, for structures of this type, are presented. The course aims to provide a critical point of view of the different methods introduced for the design of light-weight structures, firstly, considering the models employed for the realizations using traditional materials and successively evaluating a-typical and innovative prototypes. In these last cases, the use of sustainable and eco-friendly materials and the design of transportable structures for aerospace applications will be explored. The form-finding processes (FFp), such as the dynamic relaxation method, the particle spring model, the thrust network analysis, etc. will be illustrated together with their principles and their differences for the FFp of vaults, grid shells and active bending structures (FFp will be implement ed by Rhinoceros, Grasshopper, Visual-Nast ran 4D, et c.). The calculation methods and the shape generating procedures for tensegrity and origami structures will be also addressed in their fundamental outlines. The structural optimization of shells and spatial structures will be evaluated by investigating the main and most innovative methods based on the parametric and topological approaches, also by the use of NURBS sur faces. The course, finally, get the scope of identifying the most important validation procedures for these structures with respect to the criteria of local and non-local instability analysis of shells and vaults. The possible instability and coupled instability phenomenon will be studied through the application of linear and non-linear FEM models. In particular, the course will also provide an overview on the current retrofitting techniques and permanent monitoring systems, currently in use, in spatial and shell structures normally employed to cover public spaces.
