Some examples of the simultaneous use of closed-form and numerical solutions in shell structural analysis

The computational advantages of the use of different approaches -numerical and analytical ones- to the analysis of different parts of the same shell structure are discussed. Examples of large size problems that can be reduced to those more suitable to be handled by a personal related axisyrometric finite elements, local unaxisymmetric shells, geometric quasi-regular shells, infinite elements and homogenization techniques are described

The folded plate model in structural analysis. Elastic, plastic and dynamic formulations for nonprismatic structures

A specific numerical procedure for the analysis of arbitrary nonprismatic folded plate structures is presented. An elastic model is studied and compared with a harmonic solution for a prismatic structure. An extension to the plastic analysis is developed, and the influence of the structural geometry and loading pattern is analyzed. Nonprismatic practical cases, with arbitrary geometry and loading are shown, as well in the elastic range as in the plastic one. Finally, a dynamic formulation is outlined

A conceptual insight on digital paralell workshops for urban planning

The educational realm in Urban Plan ning needs a review because of the global challenges that human settlements will face in the near futu re. In this scenario, international boards of research call for the development of common frameworks of research, accredita tion, and planning best-pra ctices, that need to transcend the limits of local competences, which at the same time affect educational structures. A central issue on achieving this pursued consensus is in ternational cooperation among academic institutions, seeking global awareness on urban challenges, built equally upon a variety of context-based experiences. The rise of ICT's and digital tools are widely perceived as a great field of opportunity to establish complex and de-centralized networks of knowledge-bu ilding that can be critical to address these needs.
