ABSTRACT
A simple homogenized model based on a holonomic approach is presented, aiming at the study of the non-linear behaviour of masonry walls subjected to two-way bending. The developed discrete macro-model is based on quadrilateral rigid element discretization, where flexural deformation is allowed only at the interfaces through a system of axial and torque trusses. The behaviour of the interfaces is obviously holonomic and orthotropic with softening, because they are derived from the aforementioned homogenization strategy. At a meso-scale, the developed procedure relies on a homogenized model based on a holonomic approach. Homogenization consists in introducing averaged quantities for macroscopic strain and stress tensors. The discrete element model on a macro-scale level the out-of-plane analysis of the masonry walls will be performed through a novel discrete element system. The holonomic homogenization model allows obtaining the masonry material properties accounting the strain softening regime.
