“…This choice has been made given that this paper aims to assess the loss of performance of FRP strengthening systems bonded to masonry structures due to environmental degradation. However, the approach proposed herein can be easily extended to account for environmentally-induced degradation in the masonry material (see for example [62,63,64]), altering the masonry mechanical properties analogously to what proposed for FRP strengthening systems.…”

“…In this context, a novel coupled multiphase model for Hygro-Thermal-Chemical (HTC) analysis of masonry structures has been developed [69][70][71]. In the model, thermal effects are fully considered and a suitable modeling of the crystallization/dissolution and hydration/dehydration processes allows considering salts with hydrous and anhydrous crystals.…”

“…Such a procedure is based on the real 3D micro geometry of the porous material coming from X-ray Micro Computed Tomography images: starting from the HTC model results, it allows evaluating the mechanical effects of salt crystallization occurring at the macro-scale. Finally, in the same framework and with the aim of understanding the effects of deterioration processes caused by the environment at the scale of the building, a numerical multi-scale approach able to simulate the response of large-scale masonry walls has been developed [71]. Two scales of representation, sketched in Fig.…”

The Need of Multidisciplinary Approaches and Engineering Tools for the Development and Implementation of the Smart City Paradigm

et al. 2018

View full text Add to dashboard Cite

This paper is motivated by the concept that the successful, effective, and sustainable implementation of the Smart City paradigm requires a close cooperation among researchers with different, complementary interests and, in most cases, a multidisciplinary approach. It first briefly discusses how such a multidisciplinary methodology, transversal to various disciplines such as Architecture, Computer Science, Civil engineering, Electrical, Electronic and Telecommunication engineering, Social science and Behavioral science, etc., can be successfully employed for the development of suitable modeling tools and real solutions of such socio-technical systems. Then, the paper presents some pilot projects accomplished by the authors within the framework of some major EU and national research programs, also involving the Bologna municipality and some of the key players of the Smart City industry. Each project, characterized by different and complementary approaches/modeling tools, is illustrated along with the relevant contextualization and the advancements with respect of the state of the art.

“…Particularly, the model has been used in [35] to reproduce the results of an experimental campaign carried out on a masonry wall exposed to weather conditions for a long time. Such model has been successively extended in [36], to account for different salt solid phases in the pores, in [37], where a fully coupling between mechanical response and moisture diffusion has been considered, and in [38], where a multi-scale approach for the analysis of mechanical effects induced by salt crystallization in porous media has been presented. Although several advances have been achieved in the framework of multiphysics analysis of salt crystallization in masonry structures, only very few examples were aimed to the analysis of masonry strengthened with composites.…”
