Guidelines to improve sustainability and cultural integration of temporary hous...
Félix, Daniel; Branco, Jorge M.; Feio, A. O.Unfortunately, natural disasters have drastically increased over the last decades causing extensive material and non-material damages. The destruction of houses and the number of homeless people are some of the most visible effects of post-disaster scenarios. Housing is one of the people’s most important needs and it is also essential for their well-being. After a disaster it is crucial to supply temporary a...
Temporary housing after disasters : a state of the art survey
Félix, Daniel; Branco, Jorge M.; Feio, A. O.The number of natural disasters has drastically increased, causing great damages on buildings. A large number of houses have suffered damage and become unusable, causing a high number of homeless people. Housing reconstruction programmes play a decisive role on the disaster recovery and providing temporary housing is a crucial step of these programmes. During the reconstruction of permanent housing, it allows v...
Sistemas em madeira e derivados na reabilitação urbana em situações pós-catástrofe
Félix, Daniel; Feio, A. O.; Branco, Jorge M.Os centros históricos são elementos importantes e fundamentais de muitas cidades. Representam a sua história e evolução, sendo por isso parte essencial do Património Cultural. São contudo elementos extremamente vulneráveis, sendo vários os exemplos ao longo da história de situações imprevistas como terramotos, tsunamis, cheias, vulcões, incêndios, etc., que provocaram danos significativos nos edifícios e monume...
Capacity of a traditional timber mortise and tenon joint
Feio, A. O.; Lourenço, Paulo B.; Machado, J. S.The safety and quality of traditional timber structures mostly depends on the conditions of their connections. A testing campaign has investigated the behaviour of mortise and tenon timber joint. The present paper addresses the quantification of the strength capacity of wood-wood mortise and tenon joint by physical testing of full-scale specimens. In addition, the performance of different non-destructive techni...
Chestnut wood in compression perpendicular to the grain : non-destructive corre...
Lourenço, Paulo B.; Feio, A. O.; Machado, J. S.This paper addresses the evaluation of the compressive properties of chestnut wood under compression perpendicular to the grain, using destructive and non-destructive methods. Three non-destructive methods (ultrasonic testing, Resistograph and Pilodyn) are proposed and the possibility of their application is discussed based on the application of simple linear regression models. Timber specimens were tested up t...
Cobertura da sala do relicário no Mosteiro de Santa Cruz : notas sobre a interv...
Lourenço, Paulo B.; Feio, A. O.; Brites, Ricardo D.A alvenaria e a madeira são materiais de construção tradicionais, que surgem actualmente com interesse renovado na indústria de construção. No caso da madeira, e de um modo geral, muitos sistemas estruturais continuam a desempenhar as suas funções (embora muitos deles tenham sido substituídos por lajes aligeiradas em betão armado no decurso do século XX), o que requer frequentemente inspecções para averiguar a ...
Non-destructive evaluation of the mechanical behaviour of chestnut wood in tens...
Feio, A. O.; Lourenço, Paulo B.; Machado, J. S.The paper addresses the evaluation of strength and stiffness of chestnut wood, in tension and compression parallel to the grain, using different non-destructive techniques (ultrasounds, Resistograph and Pilodyn). Around two hundred timber specimens (divided into compression and tension tests) were tested up to failure, comprising recently sawn timber (which is now available on the market for structural purposes...
Inspection and diagnosis of historical timber structures : NDT correlations and...
Feio, A. O.Tese de doutoramento em Engenharia Civil ; The work presented in this thesis was carried out at the Civil Engineering Department of University of Minho, Portugal, at the Timber Structures Division of National Laboratory for Civil Engineering, Portugal, and at the D.I.S.T.A.F of University of Florence, Italy. In order to assess the safety of old structures and preserve their original essence as much as possible...
Compressive behavior and NDT correlations for chestnut wood (Castanea sativa Mi...
Feio, A. O.; Machado, J. S.; Lourenço, Paulo B.The goal of the present work consists in the characterization of the mechanical behavior of chestnut wood under compression perpendicular to the grain. After a review of the problems usually involved in characterizing timber under this type of loading, a mechanical test was set-up. The timber specimens used in the testing program were divided in two groups: (a) new chestnut wood (NCW), which has never been used...
Parellel to the grain behavior and NDT correlations for chestnut wood (Castanea...
Feio, A. O.; Lourenço, Paulo B.; Machado, J. S.L'obiettivo di questo lavoro è basato nella descrizione del comportamento meccanico del legno di castagno sotto compressione e traccione paralleli al grano. Dopo una revisione dei problemi addetti a caratterizzare il legname sotto questi tipi di caricamenti, una prova meccanica è stata installata. Gli esemplari del legname usati nel programma di prova sono stati divisi in due gruppi: (a) legno nuovo di castagno...
