- Effect of Spring-Mass-Damper Pedestrian Models on the Performance of Low-Frequency or Lightweight Glazed FloorsPublication . Bedon, Chiara; Santos, Filipe A.; CERIS - Polo NOVA; DEC - Departamento de Engenharia Civil; MDPI - Multidisciplinary Digital Publishing InstituteFor structural design purposes, human-induced loads on pedestrian systems can be described by several simplified (i.e., deterministic equivalent-force models) or more complex computational approaches. Among others, the Spring-Mass-Damper (SMD), Single Degree of Freedom (SDOF) model has been elaborated by several researchers to describe single pedestrians (or groups) in the form of equivalent body mass m, spring stiffness k and damping coefficient c. For all these literature SMD formulations, it is proved that the biodynamic features of walking pedestrians can be realistically reproduced, with high computational efficiency for vibration serviceability assessment of those pedestrian systems mostly sensitive to human-induced loads (i.e., with vibration frequency f1 < 8 Hz). Besides, the same SMD proposals are characterized by mostly different theoretical and experimental assumptions for calibration. On the practical side, strongly different SMD input parameters can thus be obtained for a given pedestrian. This paper focuses on a selection of literature on SMD models, especially on their dynamic effects on different structural floor systems. Four different floors are explored (F#1 and F#2 made of concrete, F#3 and F#4 of glass), with high- or low-frequency, and/or high- (>1/130th) or low- (1/4th) mass ratio, compared to the occupant. Normal walking scenarios with frequency in the range fp = 1.5–2 Hz are taken into account for a total of 100 dynamic simulations. The quantitative comparison of typical structural performance indicators for vibration serviceability assessment (i.e., acceleration peak, RMS, CREST) shows significant sensitivity to input SMD assumptions. Most importantly, the sensitivity of structural behaviours is observed for low-frequency systems, as expected, but also for low-mass structures, which (as in the case of glazed floor solutions) can be characterized by the use of lightweight modular units with relatively high vibration frequency. As such, major attention can be required for their vibrational analysis and assessment.

- Chaminés industriais de alvenaria de tijoloPublication . Cardoso, Nicole; Diaz Gonçalves, Teresa; Oliveira Santos, Teresa; Faria, PaulinaAs chaminés industriais de alvenaria de tijolo são marcos de antigas indústrias e testemunhos da história das comunidades onde estas se inseriam. Hoje estão desativadas, podendo encontrar-se um pouco por todo o território português, muitas vezes ao abandono. Há uma enorme necessidade de intervir para preservar este património que tanta história transportou, não sendo porém fácil conciliar a manutenção da imagem original com as intervenções necessárias a prevenir ou remediar os danos materiais, frequentemente profundos. Esta apresentação marca o início de um trabalho de investigação que pretende chamar a atenção para a importância de preservar e conservar estas construções de forma adequada. O trabalho incluirá uma caracterização de chaminés selecionadas e do seu estado de conservação. Seguir-se-á uma análise crítica da compatibilidade das necessárias técnicas de intervenção com conceitos fundamentais de teoria da conservação. No decurso do trabalho procurar-se-á recolher contributos e comentários de técnicos e cidadãos interessados na temática da preservação e conservação de chaminés industriais, seja em geral, seja em relação a casos locais. Para permitir essa interação, estão em criação um website e um grupo na rede social linkedin. Agradecem-se expressões de interesse, que podem ser enviadas para nc.cardoso@campus.fct.unl.pt
