Seismic-V : vernacular seismic culture in Portugal

For a long time, reactive seismic retrofitting was focused on monumental heritage and very little on vernacular architecture. In the last years, there has been a growing interest on seismic resistant design and solutions and several research units emerged to produce important research in the scientific field. However, for some time, international focus to address earthquake-damaged buildings was on intrusive te...

Estudo Prospectivo Referente aos Principais Factores de Risco de Patologia Card...

Introdução: é actualmente consensualmente reconhecido que a aterosclerose tem a sua origem na idade pediátrica ainda que as expressões clínicas da doença cardio-cérebro-vascular se manifestem apenas na idade adulta. Entre os seus principais factores de risco apontam-se entre outros, a obesidade, a hipertensão e um perfil lipídico sérico adverso. Tais factores de risco evidenciam uma notória estabilidade relativ...

Investigating Population Structure of Sea Lamprey (Petromyzon marinus, L.) in W...

This study hypothesizes the existence of three groups of sea lamprey Petromyzon marinus L. in Portugal (North/Central group, Tagus group, and Guadiana group), possibly promoted by seabed topography isolation during the oceanic phase of the life cycle. Within this context, our purpose was to analyze the existence of a stock structure on sea lamprey populations sampled in the major Portuguese river basins using b...

Reliability analysis of a timber truss system subjected to decay

Assessing the safety of existing timber structures is of paramount importance for taking reliable decisions on repair actions and their extent. The results obtained through semi-probabilistic methods are unrealistic, as the partial safety factors present in codes are calibrated considering the uncertainty exhibited by new structures. In order to overcome these limitations, and also to include the e ects of deca...

Seismic assessment of St. James church by means of pushover analysis : before a...

The paper presents a numerical study for the seismic assessment of the St James Church in Christchurch, New Zealand affected by the recent 2011 earthquake and subsequent aftershocks. The structural behaviour of the Church has been evaluated using the finite element modelling technique, in which the nonlinear behaviour of masonry has been taken into account by proper constitutive assumptions. Two numerical model...

Assessment of the structural properties of timber members in situ : a probabili...

The assessment of the structural performance of existing timber structures is dependent, among other factors, on the capacity to evaluate the physical and mechanical properties of structural timber elements in situ. This paper discusses the possibilities/advantages of using a probabilistic approach to obtain a more reliable prediction of the reference properties of these timber members in situ. The presented ap...
