“…e model can be extended to masonry by assuming a heterogeneous material as a continuous one, with bricks and mortar considered together as a single homogenous material through a total strain rotating crack model approach [52]. Recently [49], the FE-TRSCM has been adopted by authors for modeling in-plane loaded masonry and compared with a simple rigid block model and a combined FE-DE model. Such a model has been also compared by other authors with other numerical tools for assessing the seismic behavior of unreinforced masonry [48].…”

“…A further comparison between the results given by the proposed refined rigid block model with respect to the original one is briefly described in appendix in terms of loaddisplacement curves. For further details on the results given by the standard rigid block model, the recent contribution by authors [49] can be taken into consideration.…”

“…e aim of this work is to validate the proposed improvements of an existing rigid block model by performing several numerical tests and comparing the results of the updated model with respect to existing laboratory results and other accurate numerical results. e calibration already performed by the authors for rigid, FE/DE, and FE-TRSCM models [49] is extended to the case of the updated rigid block model. Before performing tests on masonry walls, the nonlinear behavior of mortar joints is evaluated for first by performing some numerical tests on two blocks specimens.…”

In this work, a refined rigid block model is proposed for studying the in-plane behavior of regular masonry. The rigid block model is based on an existing discrete/rigid model with rigid blocks and elastoplastic interfaces that already proven its effectiveness in representing masonry behavior in linear and nonlinear fields. In this case, the proposed model is improved by assuming rigid quadrilateral elements connected by one-dimensional nonlinear interfaces, which are adopted both to represent mortar (or dry) joints between the blocks and also to represent inner potential cracks into the blocks. Furthermore, the softening behavior of interfaces in tension and shear is taken into account. Several numerical tests are performed by considering masonry panels with regular texture subjected to compression and shear. Particular attention is given to the collapse mechanisms and the pushover curves obtained numerically and compared with existing numerical and laboratory results. Furthermore, the numerical tests aim to evaluate the applicability limits of the proposed model with respect to existing results.

“…The approach here adopted follows the lines developed in previous works of some of the authors, and in particular in (Baraldi et al, 2018a). Masonry panels are modeled as an assemblage of deformable bricks connected by zerothickness Mohr-Coulomb interfaces.…”
