International bibliography on conservation usually refers that mortars made with lime putty with long extinction periods behave better than others made with the current dry hydrated limes. In order to evaluate this assess, an experimental study of lime mortars was carried out, using dry hydrated lime and two lime putties. It becomes clear that the use of lime putties with long extinction periods in mortars allow better performances, particularly in applicability and resistance to sulphates.

This research aims to evaluate the intervention techniques currently adopted for the traditional timber frame wall, using a case study in downtown Lisbon. Different rehabilitation solutions were identified and evaluated through a multi-criteria decision analysis using dedicated software (M-Macbeth, Measuring Attractiveness by a Categorical-Based Evaluation technique). Five evaluation criteria, i.e. material compatibility and permanence, structural reliability and authenticity, and visual-tactile appearance, were selected for this specific context. A multidisciplinary panel of experts in conservation science were consulted for defining the performance descriptors, evaluation levels, and weightings of these criteria. 2 Results show that Macbeth is a useful decision-aid capable of handling multiple outputs generated from qualitative expert judgments. Lastly, the predominance of five best-scoring interventions within three design-related scenarios is discussed. Highlights: • Overview of rehabilitation techniques for traditional timber frame walls in Pombalino buildings (late-18th century); • Ranking of repair and strengthening measures through a multi-criteria model; • Presenting a multi-criteria procedure capable of evaluating several construction techniques within design-related scenarios; • Recommendations for best rehabilitation techniques for these traditional structural components.

Vitruvius FabLab -IUL I In nt tr ro od du uc ct ti io on n Over the past decades, the development of new technologies and the emergence of sustainable/integrated digital tools for visualization, representation and fabrication have played crucial roles in architectural design, as a new paradigm at various levels: education, research and architectural practice. The digital revolution has transformed not only the process of architectural thinking but also the making. Architecture schools around the world are creating digital fabrication laboratories to provide their students with the skills to support new learning processes, scientific innovation and development linked to architectural practice and the building industry. Digital technologies have released a multiplicity of new career opportunities for graduates and advanced architectural education. Digital methods enable architects to create complex parametric modeling geometries; generate construction information directly from design; test its performance virtually and physically; and produce full-scale models of their designs. Thus, it has been necessary to introduce new architectural curricula in academia and new strategies to approach technology, implement digital thinking, and foster collaborative environments and digital methods. The main goal has been to explore the new digital technologies and their contribution to solving some of the challenges presented to society and architecture. Social responsibility requires greater sensitivity to innovation. Digital design sensibility must encompass the school culture [Cheng 2003]. The progress of architectural practice

A deep understanding of the architectural heritage in all its aspects is essential in order to evaluate a correct conservation and rehabilitation approach. The heritage rehabilitation requires a careful analysis of the available techniques for structural improvement, seeking a weighted compromise between the paradigms of contemporary use and the cultural value of the historical building. This paper briefly discusses the seismic-resistant heritage of the 18 th C, circumscribed in Lisbon's Baixa Pombalina (post 1755) and case baraccate of southern Italy (post 1783). A comparison of these anti-seismic systems is discussed through the architectural principles and the mechanical behaviour. It is shown that, despite the wide diversity of cases and the different geohistorical conditioning, both systems arise from an intuition of the compound seismic efficiency, Enlightenment pragmatism and an interpretation of the classic composition code. Two specific case studies, a private building in Baixa Pombalina (Lisbon) and the Bishop's Palace of Mileto (Calabria region) are compared. We briefly analyze: i) configuration and structural principles; ii) characteristics of the materials; iii) seismic behaviour. A standardized spatial morphology closely linked to traditional construction techniques positively determines the seismic response and it is one of the key common factors in this heritage to be preserved.Keywords: timber structure, earthquake resistant structures, gaiola pombalina, casa baraccata, architectural heritage. Research aimsThe aim is to establish analogies and differences between composite structures in the Mediterranean area to perform a critical analysis for the safeguard of the architectural heritage, dated from the late 18 th C. This work contributes to multidisciplinary knowledge of the traditional techniques that influence the spatial configuration and represent an identifying cultural element. We want to deepen the knowledge related to the impact of the original architectural and technical solutions in the seismic response of the building, through the analysis of the two models in the light of their geometrical and structural characteristics. The comparison of the anti-seismic heritage, in Italy and in Portugal, should help to clarify a current methodological approach to the heritage safeguard. From a state of art that integrates areas generally addressed separately, this paper focuses on two specific cases, analysed from a typological starting-point. The selection of these two specific cases depended also on the actual possibility to observe directly the structure, alongside the historical and experimental research. Differences arise in the two cases related to the development of density of occupancy, the walls structure and the mechanical behaviour.
