Resumo
SSince the 1960's, in the Recife Metropolitan Region of Brazil, it was noticed an increase in building construction in "non-load bearing masonry". This sort of masonry consists of hollow ceramic bricks, or concrete blocks, seated with horizontal holes, 0.09 m thick for use mainly in residential building constructions up to four floors. One of the main characteristics of the constructive process is that the walls should not be demolished or opened, except for what has already been established on the project, or it will cause a serious risk of compromising the stability of the construction. This paper aims to do a structural analysis on the impacts caused by large openings on non-load bearing masonry, through computational models based on the Finite Element Method. It concludes that through the application of the studied model it is possible to analyze structural problems caused by the openings, allowing to make known how the buildings structure will behave. It is also possible to predict the extension of the impact on the whole structure due to modification, besides allowing to know to what extent the building could withstand, to the tension state due to the removal of part of the masonry, without collapsing.
