Selection remains driven by field scenarios, cost restrictions, and level of result detail needed. This paper contributes to this discussion by comparing micro and macro models of buildings subjected to excavation-induced ground movements. A smeared crack model is used to represent cracking in bricks and mortar joints, and the brick structure is modelled as an isotropic continuum. In the macro model, a homogeneous procedure employed is an alternative approach for determining mechanical properties of a basic cell. Results are compared to large-scale modelling work. Respective advantages and disadvantages are shown.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Keywords:||Micro modeling; Macro modeling; Homogenization technique; Smeared crack model; Large-scale model test; Building damage||Subject LCSH:||Earth movements and building
