Finite element modelling of reinforced masonry walls under axial compression

This paper presents the development of 3D finite element (FE) technique to model and analyse reinforced masonry (RM) walls under axial compression. The Arc-length algorithm integrated with initial geometric imperfection has been used nonlinear response both embedded steel that RM wall allow for occurrence buckling concentric A segmental modelling was developed consider material nonlinearities each component a such as block, mortar, grout reinforcement bars. parameters were calibrated using experimental testing program previously conducted by authors in which three series different slenderness ratios (4, 7 12) tested applicability models verified data terms load-deflection responses strain vertical It determined able capture reasonable accuracy. Further, FE predict higher (21, 26, 32 42) examine probable taller walls. failure modes ultimate capacity slender have reported potential are discussed against existing code provisions.
