“…Therefore, non-linear static analyses account for both the actual force-resisting system of the building, in particular the overstrength, and the actual energy-dissipation system of the building, in particular not only the plastic dissipation (Foraboschi and Vanin, 2013a). In the case of masonry buildings, moreover, linear analyses suffer from the absence of correlation between linear behavior and ultimate limit state.…”

“…Among them are the 3D limit analysis approach by rigid macro-blocks (Orduña and Lourenço, 2005a and b) (Orduña et al 2008) and the strut-and-tie model (Foraboschi and Vanin, 2013a). The first approach is based on a rigid-perfectly plastic material that does not need parameters of stiffness and softening, only strength parameters.…”

“…However, the lower bound theorem can be extended to masonry structures, under the assumption that masonry has an elasto-plastic compression behavior (or perfectly elastic) and a no-tension behavior, which is an assumption that suits masonry adequately (Foraboschi and Vanin, 2013a).…”

The 3D FE models are calibrated with experimental data and assessed through nonlinear static approaches including the seismic demand and an accurate validated masonry model. Based on an extensive parametric study on different configurations of old masonry towers, it is selected an optimal prestressing force and device. The Colonial towers are retrofitted with four prestressing devices of FRPs to convert them into a high energy-dissipative reinforced masonry. The external vertical prestressing is included at key points identified in the seismic vulnerability assessment. This technique is in compliance with the demand for architectural conservation and may be located without drilling and unbounded in order to be fully removable. The seismic performance is enhanced by increasing force, displacement and internal confinement. It is observed an upgrading of 35% and 20% of displacement capacity. With these results it is corroborated that external vertical prestressing allows a substantial increment of ductility for seismic energy dissipation purposes.

“…For instance, Fobaroschi and Vanin developed a new nonlinear static model for determining the lateral capacity of masonry buildings based on this theorem. This model can simulate the behavior of masonry in different stages; uncracked, cracked and softening conditions [20]. Salmanpour et al through a state of the art article, investigated the deformation capacity of the URM walls.…”

Addessi et al [20] developed an equivalent frame model for nonlinear analysis of URM panels subjected to lateral inplane loads. They developed sectional inelastic response of the masonry piers by assuming an inelastic response for the masonry under monotonic loadings.…”

According to the importance of seismic evaluation of existing unreinforced masonry (URM) buildings, researchers have been interested in numerical modelling of these types of structures and their components. On the other hand, in seismic performance evaluation and retrofitting codes which are mostly based on Performance Based Seismic Design (PBSD), different analysis methods such as linear and nonlinear, static and dynamic analyses are employed. Therefore, simple equivalent frame models with lower computational cost are very useful for modelling and analysis of unreinforced masonry buildings. In this article, a simple equivalent truss model is proposed for modelling and analysis of an unreinforced masonry wall with sliding shear failure as the governing in-plane failure mode. The model is developed according to an analogy between the internal forces in a triangular truss and the Mohr-Coulomb failure criteria. Then, the proposed model is generalized for modelling and push over analysis of combinations of walls. Finally, the modelling procedure is applied for push over analysis of an unreinforced masonry wall consists of some piers and the push over curve of the wall is determined and discussed.
