Lajes mistas de madeira-betão

Abstract

Em trabalhos de reabilitação de edifícios antigos é prática comum a substituição dos pavimentos de madeira por lajes de betão. Esta solução produz um aumento de massa que pode conduzir a uma significativa diminuição da segurança estrutural. Estudos recentes mostram que a utilização de pisos mistos de madeira-betão, reutilizando ou não as traves existentes, conduz a soluções mais leves e melhor enquadradas na arquitectura. O comportamento deste tipo de lajes é fortemente condicionado pela ligação madeira-betão. Neste trabalho, analisam-se as tipologias mais correntes, os sistemas de ligação disponíveis e a metodologia de cálculo preconizada pelo Eurocódigo 5 para o dimensionamento de lajes mistas de madeira-betão, apresentando-se a resolução de um exemplo numérico. São ainda descritas novas tipologias estruturais, em particular, aquelas orientadas para a pré-fabricação.
