“…For the evaluation of class scores and parameter weights, a MCDM technique was used, specifically the Analytic Hierarchy Process (AHP) introduced by (Saaty, 1980). Many researchers used the AHP technique, which requires expert judgement to determine weight parameters, see (Alizadeh et al, 2018;Bahadori et al, 2017;Fontenele et al, 2023). According to (Dean, 2022), the AHP method requires that the relative importance of each criterion with respect to the objective, is determined by a series of pairwise comparisons of criteria.…”

“…Indeed, historical sites are particularly susceptible because of their physical or tangible, as well as immaterial or intangible value. In addition to their economic value, historic centres, as part of cultural heritage, allow people to understand and experience culture, customs and traditions, art, religion, and history, as well as contribute to community identity and memory, and a sense of belonging (Fontenele et al, 2023;Puncello and Caprili, 2023). Assessing the seismic vulnerability of structures in historic areas is very difficult for a variety of reasons.…”

“…Municipalities face the challenge of managing risk on a large scale, necessitating simple approaches that allow them to prioritise interventions and mitigation strategies against various objectives, and they are typically required to make decisions based on specific criteria. However, this may be managed using approaches such as Multi-Criteria Decision Making (MCDM) procedures, which allow experts to analyse a plan by taking into consideration multiple interests, as well as the interplay of several, often conflicting, objectives and decision criteria (Alizadeh et al, 2018;Dean, 2022;Fontenele et al, 2023). As a result, the current study deals with evaluating the seismic vulnerability of the existing building stock using a feasible, robust and reproducible MCDM approach that explicitly incorporates multiple objectives and decision criteria into the analysis.…”

Seismic events have shown to be exceedingly damaging to structures over time, with serious social and economic consequences. As a result, large-scale seismic risk assessments are essential for reducing the potential damage from future earthquakes. Therefore, the proposed study attempts to examine the vulnerability and risk of unreinforced masonry buildings (URM) placed in aggregate conditions in a historical area of the city centre of Lisbon. To this purpose, a comprehensive exposure model was developed combining satellite remote sensing, GIS software, and census data. Subsequently, seismic hazard was evaluated in the area, considering both Peak Ground Acceleration (PGA) and macro-seismic intensity for different return periods (i.e. 2-50-100-475-975-2500-5000 years). Vulnerability was assessed by introducing a novel approach to earthquake risk assessment using Multi-Criteria Decision-Making methodologies. Specifically, the method employs the Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) computational methods to evaluate parameter weights and vulnerability index. Damage scenarios, fragility curves and mean damage ratios curves were provided to offer an overview of the vulnerability of the assets exposed to risk. Finally, the expected consequences were evaluated in terms of direct economic losses showing an economic loss of 595 M€ for a 475-years return period, while 1108 M€ for 5000-years. This study significantly enhances seismic risk analysis for urban areas by introducing a Multi-Criteria Approach. This method simplifies vulnerability assessment, ensuring ease of application and reproducibility. Its insights offer valuable support for disaster risk management decisions, facilitating the implementation of resilience and risk-reduction strategies.

Considerando a importância do estudo e documentação de edificações históricas, este trabalho apresenta resultados de prospecção estratigráfica de pintura e de simulação, através do software WUFI Pro® 6.6, da temperatura superficial externa das fachadas do edifício Château, localizado na UFRGS, Porto Alegre. Suas fachadas são revestidas em argamassa, tendo sido identificadas camadas de pintura branca, amarela e cinza. A fachada noroeste apresentou maiores temperaturas que a sudeste e a temperatura superficial média anual das fachadas foi superior à média da temperatura do ar exterior. A cor cinza gerou média anual de temperatura superficial maior que as cores branca e amarela.

“…It should be noted that over the years old buildings tend to present vulnerabilities, resulting from the time of use, as well as the degradation of materials. In this sense, it is of vital importance that speci c methodologies be adopted to achieve the proposed evaluation objective (Fontenele et al, 2023).…”

Characterization of historic masonry of the twentieth century: Casa Salinger, Blumenau-SC

The preservation of the historical heritage of a locality is of paramount importance for the identity of a society to remain alive, valuing knowledge of history, cultural and social elements, becoming a record for its successors. The Salinger house is a listed heritage site in the city of Blumenau, Santa Catarina, Brazil, a case study for the present work given the importance of knowing the materials and methods used in the construction so that its restoration can be carried out later. For this reason, the aim of this study is to characterize the materials used in the masonry of this historic building from the 20th century and to evaluate the mechanical properties of walls built with the material. With that in mind, the ceramic blocks were characterized as to their geometry, speci c mass, water absorption and mechanical strength. In addition, for the mortar, a mix used at the time was de ned, without the addition of Portland cement, only with lime, whose mechanical behaviour in tension and compression was measured. Finally, mechanical characterization tests were carried out on walls made with these materials, demonstrating that the system built at the time did not have a structural function, being functioning only with bearing capacity. This result was already expected since in the half-timbered constructions of the time, the blocks served only as closing masonry.
