Development of sandwich panels of customized functionalities for the rehabilitation of the built patrimony

Considering that the future of the construction sector in most European countries will mainly lie in the renovation of the existing building stock, in the next coming years thousands of energy inefficient buildings will need renovation to force EU member states to reach the EU 2020 targets and implement the Energy Performance of Buildings Directive (EPBD). Seeing the actual crisis in the construction sector as an opportunity, this work aims to develop a concept for prefabricated customizable sandwich panels for the multifunctional renovation of buildings, focusing also on technological innovation. More than a conventional solution, this proposal aims to combine sustainable and recycled building materials, available technologies and systems with advanced design and manufacturing tools within an integrated and mass-customizable approach of advanced building renovation prefabricated solutions. The adoption of these new proposed solutions would improve the living standards of the inhabitants of our cities, reducing energy inefficiency and other existing construction/renovation problems, while enabling some advanced features like the incorporation of technical modules that could even monitor the building performance during its full lifetime and the living conditions of its occupants.

Painéis sandwich customizados para a reabilitaçãoo do património edificado

Entendendo a presente crise do setor da construção como uma oportunidade para promover a reabilitação do parque habitacional existente, este trabalho tem como objetivo o desenvolvimento de um conceito de painéis sandwich customizáveis para a renovação multifuncional de edifícios. Mais do que uma solução convencional, esta proposta visa combinar materiais de construção sustentáveis, sistemas e tecnologias disponíveis com ferramentas de fabrico e design avançado, numa abordagem integrada e personalizada de soluções de pré-fabricação em massa para a reabilitação do parque habitacional. Pretende-se com a adoção das soluções propostas contribuir não só para a redução da ineficiência energética dos edifícios, mas também minimizar os problemas de construção existentes, estudando também a incorporação na fachada de módulos avançados, como painéis solares, para melhorar o seu desempenho energético.

Effective stiffness behaviour of sandwich beams under uncoupled bending and torsion loadings

Sandwich geometries, mainly in the form of panels and beams, are commonly applied in various transportation industries, such as aerospace, aeronautic and automotive. Sandwich geometries represent important advantages in structural applications, namely high specific stiffness, low weight, and possibility of design optimization prior to manufacturing. The aim of this paper is to uncover the influence of the number of reinforcements (ribs), and of the thickness on the mechanical behavior of all-metal sandwich panels subjected to uncoupled bending and torsion loadings. In this study, four geometries are compared. The orientation of the reinforcements and the effect of transversal ribs are also considered in this study. It is shown that the all the relations are non-linear, despite the elastic nature of the analysis in the Finite Element software ANSYS MECHANICAL APDL.
