No full textComplete 3D models of existing masonry structures can be obtained assembling 2-nodes macro-elements, representing the non-linear behavior of masonry panels and piers. This modeling strategy has been implemented in the TREMURI program with non-linear static and dynamic analysis procedures requiring limited computational loads. By means of internal variables, the macro-element considers both the shear-sliding damage failure mode and its evolution, controlling the strength deterioration and the stiffness degradation, and rocking mechanisms, with toe crushing effect. Masonry building models can be obtained assembling plane structures, walls and floors
