Abstract

In the last decade has been a global crisis in the construction sector and a substantial reduction of new construction, particularly in Portugal, being the stone sector one of the most affected in terms of production. This period of low demand precedes a period of abundance in this industry, characterized mainly by the mass production of standard products. The current market is increasingly focused on the demand for innovative products that stand out in aesthetic and functional terms, favoring, in the case of building facades, the use of large and reduced thickness panels and presenting versatility in architectural terms. In this context, this thesis intends to continue the study, initiated in 2008, in a R&D project in a consortium between the Institute of Engineering of the Faculty of Porto and the companies Frontwave S.A. and Solancis, of a solution of large natural stone panels, originally designed for ventilated facade. The result of this project originated a validation of the basic concept for the design of the panels, which is based on the application of prestress forces for the joining of natural stone slabs. This experimental work seeks to fill the main shortcomings presented by the panel in terms of its structural response, ease of production, fast assembly and energy performance. For this, a numerical simulation tool will be used to create a finite element model, whose validation will be carried out by means of mechanical tests on the panels.
