Systematisation of seismic retrofitting in vernacular architecture
Lima, A.; Correia, M. R.; Gomes, F.; Carlos, G. D.; Viana, D; Lourenço, Paulo B.; Varum, H.This paper aims to identify and to systematize the data obtained during the working process of the research project 'SEISMIC-V –Vernacular Seismic Culture in Portugal' in terms of seismic- retrofitting elements earthquake -resistant reinforcement implemented in vernacular buildings. The data will be distinguished based on the structural seismic strengthening and according to the following criteria: strengthenin...
Common damages and recommendations for the seismic retrofitting of vernacular d...
Correia, M. R.; Varum, H.; Lourenço, Paulo B.This closure chapter acknowledges the most common retrofitting elements and measures identified in vernacular architecture. It enhances common systematic structural damage and failure mechanisms during earthquakes, relating them with probable causes, and establishing general recommend ations to consider in preventive and reactive actions. Also, recommendations for the design and detailing of new construction in...
Seismic behaviour assessment of vernacular isolated buildings
Ortega Heras, Javier; Vasconcelos, Graça; Lourenço, Paulo B.; Rodrigues, Hugo; Varum, HumbertoThis paper presents the numerical seismic analysis of isolated vernacular buildings characteristic of the Alentejo region, which is considered a medium seismic hazard region in Portugal.A representative isolated building was selected from a database, and a geometric model was defined for the numerical pushover analysis. Subsequently, a parametric analysis was carried out to assess the influence of distinct para...
Systematisation of seismic mitigation planning at urban scale
Viana, D. L.; Lima, A.; Carlos, G. D.; Gomes, F.; Correia, M. R.; Lourenço, Paulo B.; Varum, H.This chapter explores the relation between the seismic mitigation planning that was developed to contribute to minimise effects at urban scale, which arise within the seismic impact. In this sense, it deepens the notion that interdependence, solidarity and cohesion of the different morphological constituents promote a better prepared built fabric, when facing catastrophic phenomena of seismic origin. Preventive...
Seismic behaviour analysis and retrofitting of a row building
Barros, R. S.; Costa, A; Varum, H; Rodrigues, H; Lourenço, Paulo B.; Vasconcelos, GraçaRammed earth is one of the oldest building materials in the world and is present in Portugal with a particular focus in the South of the country. The mechanical properties and the structural behavior of rammed earth constructions have been the subject of study of many researchers in the recent years. This study is part of a broader research on vernacular seismic culture in Portugal. Numerical analyzes were carr...
Evaluation of seismic vulnerability assessment parameters for portuguese vernac...
Ortega Heras, Javier; Vasconcelos, Graça; Lourenço, Paulo B.; Correia, Mariana; Rodrigues, Hugo; Varum, HumbertoConsidering that vernacular architecture may bear important lessons on hazard mitigation and that well-constructed examples showing traditional seismic resistant features can present far less vulnerability than expected, this study aims at understanding the resisting mechanisms and seismic behavior of vernacular buildings through detailed finite element modeling and nonlinear static (pushover) analysis. This pa...
Seismic behavior of an old masonry building in Vila Real de Santo António, Port...
Ortega Heras, Javier; Vasconcelos, Graça; Rodrigues, Hugo; Correia, M.Vila Real de Santo António is located in the Algarve region and was erected ex novo at the end of the 18th Century, after the 1755 Lisbon earthquake, following a Pombaline development that showed seismic concern at an urban and architectural level. However, most of the original constructions have been subjected to continuous alterations or even substituted for new ones. The first building built in the town was ...
Local seismic cultures: the use of timber frame structures in the south of Port...
Ortega Heras, Javier; Vasconcelos, Graça; Rodrigues, Hugo; Correia, MarianaGiven the fact that using timber frame structures has proven to improve the seismic behavior of vernacular architecture, as has been reported in past earthquakes in many countries, its preservation as a traditional earthquake resistant practice is important. This paper firstly intends to evaluate whether the use of timber frames as a traditional seismic resistant technique for vernacular architecture in the Sou...
Influence of the freeze-thaw cycles on the physical and mechanical properties o...
Martins, L.; Vasconcelos, Graça; Lourenço, Paulo B.; Palha, Carlos Alberto Oliveira FernandesStone masonry buildings provide evidence of the cultural and historical values at the time. Therefore, it is important to preserve the stone of these buildings to harmful environment conditions like freeze-thaw and salt crystallization cycles, air pollution, and excessive and frequent rain or snowfall, which can lead to decay processes that endanger the future of architectural heritage. Thus, it is important to...
Traditional earthquake resistant techniques for vernacular architecture and loc...
Ortega Heras, Javier; Vasconcelos, Graça; Rodrigues, Hugo; Correia, Mariana; Lourenço, Paulo B.Specific architectural elements can be identified in constructions located in regions frequently exposed to earthquakes. These earthquake resistant features were developed empirically by local communities to protect their built-up environment. Research in these traditional earthquake resistant practices, resulting from a local seismic culture, is a relevant and positive approach, since it focuses on the strengt...
