Abstract (EN): The main objective of this paper is to demonstrate how computer simulations of laboratory tests can be useful for studying the compressive behaviour of masonry systems, made with materials with different properties, without consuming too many laboratory resources. This paper describes a sensitivity analysis applied successfully to a case study, namely in a shell bedded masonry system made with lightweight concrete units that was developed in Portugal for single leaf walls. The sensitivity analysis consisted in computer simulations of simple compressive tests on masonry through the use of 3D Finite Element Method and non-linear constitutive model, which was calibrated through a small number of laboratory tests carried on masonry samples and masonry materials. In the analysis some variations on the properties of the masonry materials (units and joints) was considered, and the results obtained are presented and discussed.
