A simple homogenization approach accounting for mortar joint damaging is presented, suitable to analyse entire panels in two-way bending in the non-linear dynamic field. A rectangular running bond elementary cell (RVE) is subdivided into several layers along the thickness and, for each layer, a discretization where bricks are meshed with plane-stress three-noded triangular elements and joints are red...
Masonry is a composite material composed of individual units laid in and bound together by mortar. Appropriate Understanding of masonry material properties results in secure and efficient protection and strengthening of historical structures. Due to high computation costs and difficulties deal with detailed modelling of masonry structures, few studies are available in open literature dedicated to mic...
Box-buildings are structural masonry buildings named as such because of their shape. There are around 5,000 of them in Recife, Brazil. This paper presents a safety analysis of one box-building that suffered collapse on December 2007. The research aims at quantifying the safety of this type of existing buildings and at better understanding their structural behavior to try to identify the reasons for t...
During the past decade, several approaches have been proposed to investigate the response of masonry structures strengthened by externally bonded Fiber Reinforced Polymer (FRP) reinforcements. Nowadays, regardless of the great efforts made, scarce information are available on the delamination behavior of reinforced curved substrates. An experimental and numerical study is presented herein, focusing o...
Neste artigo, propomo-nos relatar o percurso efetuado durante os seis meses de Estágio Curricular da Licenciatura em Educação da Universidade do Minho (UM), que decorreu no ano letivo 2007/2008 no Gabinete de Apoio ao Estudante com Deficiência (GAED)1, desta mesma instituição. O Projeto desenvolvido intitula-se A Diferença em Primeiro Plano: um pequeno passo rumo à Inclusão e teve como principais problem...
