Renovadas soluções residenciais para as pessoas idosas
Depois de um conjunto de notas introdutórias e de apresentação ao estudo global intitulado Programa de Habitação Adaptável Intergeracional desenvolvido num quadro Cooperativo e a Custos Controlados (PHAI3C), desenvolvem-se, primeiro, alguns aspetos associados às alternativas tipológicas residenciais à disposição dos idosos europeus, abordando-se, em seguida, a relação entre as escalas do habitar e os novos tipos habitacionais ligados aos idosos e rematando-se o texto com uma reflexão sobre a relação entre novas escolhas residenciais e novas formas de habitar.Nesta última temática desenvolvem-se, sequencialmente, quatro temas: a habitação dos idosos

Road Pavement, Road Pollution, and Sustainability under Climate Change Increased Temperature
This paper presents a multidisciplinary approach to understand the impacts of temperatureincrease on the retention of particulate pollutants, such as heavy metals and microplastics, by the roadpavement material. A soil with a particle size distribution similar to road dust was selected. A WheelTracking device was used to assess the permanent deformation behavior of prismatic specimens andthe retention of the dust, at controlled temperatures of 40 C and 60 C, likely to occur on pavementin the future. The soil representing road pollutants was placed at the top of the slabs prior to theWheel Tracking Test (WTT), based on the European Standard EN 12697-22:2020. After the WTT, twocommon methods were used, in order to evaluate the soil retention (pollution accumulation) onroad pavement. The results confirm that the viscoelastic behavior of bituminous mixtures underincreased temperatures can contribute to particle retention at the pavement. Future studies areneeded to understand the phenomena, the retention characteristics by different bituminous mixtures,and the efficiency of pollutants capture. The work opens the opportunity to develop innovative roadpavement bituminous mixtures that can reduce the discharge of road particulate pollutants, and haveincreased resilience and sustainability in extreme weather conditions.

SARClust
Interferometric Synthetic Aperture Radar (InSAR) has proved its efficiency for displacementmonitoring in urban areas. However, the large volume of data generated by this technology turnsthe retrieval of information useful for structure monitoring into a big data problem. In this study, anew tool (SARClust) to analyze InSAR displacement time series is proposed. The tool performs theclustering of persistent scatterers (PSs) based on dissimilarities between their displacement time seriesevaluated through dynamic time warping. This strategy leads to the formation of clusters containingPSs with similar displacements, which can be analyzed together, reducing data dimensionality, andfacilitating the identification of displacement patterns potentially related to structural damage. Aproof of concept was performed for downtown Lisbon, Portugal, where ten distinct displacementpatterns were identified. A relationship between clusters presenting centimeter-level displacementsand buildings located on steep slopes was observed. The results were validated through visualinspections and comparison with another tool for time series analysis. Agreement was found inboth cases. The innovation in this study is the attention brought to SARClust

Shared e-scooters and the promotion of equity across urban public spaces - A case study in Braga, Portugal
Shared e-scooters were introduced in urban public spaces as a way to promote a modal shift from cars in short-distance trips, as well as to improve sustainability, resilience, and equity in urban transport. However, the expansion of shared e-scooter services in 2019 proved that this mode of transport, without integrated planning strategies, can bring some problems to cities, which are related to the illegal parking of e-scooters, an increase in head injuries, and the lack of population diversity among users. Regarding the latest, this research work aims at conducting a case study in the city of Braga, Portugal to reveal who the actual and potential users of shared e-scooters are and how their socioeconomic profile (e.g., gender, age, income range, literacy, occupation) and usage patterns related to the ones found in other cities. For this, a revealed preference survey was deployed on the case study site, and the respondents

Steel bars complying with Eurocode 2 used in reinforced concrete in Portugal. Variation of their yield strength with the rebar diameter
The yield strength of the steel rebars is one of their essential characteristics considered in the safety checking of reinforced concrete structures. It may present substantial variations, due to the influence of different factors This paper presents a statistical study of the yield strength Re of A500 steel rebars used in Portugal, from three different ductility classes according to the Eurocode 2. The statistical distributions of Re are based on a very large collection of more than 30 000 test results, obtained from 1994 to 2019. These rebars were produced by several dozens of different manufacturers, mostly from foreign countries. The detailed data presented here, about the main statistical parameters of the Re distributions and their variation with the rebars grade and diameter, for instance, may be useful for different studies,such as structural refurbishment projects to evaluate the safety of existing structures, in their actual state or after their restoration.
