Buckling behaviour of structural insulating sandwich walls with textile reinforced cement faces

Loadbearing insulating sandwich panels with Textile Reinforced Cement (TRC) faces can combine the structural and insulating performance of a conventional wall configuration in one lightweight element. This makes them very suitable as a new type of wall element for low- and high rise residential buildings. By combining 2D and 3D textiles in the TRC faces the performance of the panels can even be improved. This paper presents a preliminary investigation of the buckling behaviour of large-scale sandwich panels with combined 3D and 2D TRC faces. The large-scale experiment is compared with an analytical model. This paper shows that further in depth investigations are needed with regard to the experimental test set-up (boundary conditions) in order to establish a better agreement with the analytical model.
