“…For these reasons interface elements found broad application in the numerical analysis of masonry structures [18,19,20,21,22,23,24,25,26,27] and they are still currently object of investigation [28,29]. Discrete element models (DEM) represent a further numerical strategy, utilized to analyse the mechanical behaviour of systems made of particles, blocks or multiple bodies, which appears suitable for masonry structures [30,31,32,33,34,35,36].…”

ABSTRACTIn this paper, a 3D detailed micro-model for the in-plane and out-of-plane numerical analysis of masonry structures is proposed. Representative Elements consisting of one brick and few mortar layers are explicitly modelled using 3D solid finite elements obeying to plastic-damage constitutive laws (one for brick and one for mortar) conceived in the framework of nonassociated plasticity. This permits to represent the brick and mortar mechanical behaviour when cracking and/or crushing occur. Representative Elements are assembled, accounting for any actual 3D through-thickness arrangement of masonry, by means of zero-thickness cohesive interfaces based on the contact penalty method. In the pre-failure of interfaces, all the significant deformability of the system is addressed to the 3D finite elements. A Mohr-Coulomb failure surface with tension cut-off is adopted. The post-failure interfacial response is characterized by a cohesive behaviour in tension and a cohesive-frictional behaviour in shear, which appears consistent with small-scale tests outcomes. Experimental-numerical comparisons are provided for the in-plane and out-of-plane behaviour of masonry panels. The accuracy and the potentialities of the modelling approach are shown. The direct characterization of all the model parameters from small-scale tests, as well as their clear mechanical meaning constitute further appealing qualities of the model proposed.

The improvement effect of a new strengthening strategy on dynamic action of masonry structure, by installing prefabricated concrete walls on the outer facades, is validated by shaking table test presented in this paper. We carried out dynamic tests of two geometrically identical five-story reduced scaled models, including an unstrengthened and a strengthened masonry model. The experimental analysis encompasses seismic performances such as cracking patterns, failure mechanisms, amplification factors of acceleration, and displacements. The results show that the strengthened masonry structure shows much more excellent seismic capacity when compared with the unstrengthened one.

This work presents a novel numerical model to simulate the failure process in masonry structures subjected to static loads via finite element method. Brick and mortar joints are modeled separately with their own constitutive equations. Interface finite element with high aspect ratio are used to simulate the mortar interface and inserted by the mesh fragmentation technique. The main advantage of this strategy is supported by the fact that, as the aspect ratio of a standard low-order solid finite element increases, the element strains also increase, approaching the same kinematics as the Continuum Strong Discontinuity Approach. A constitutive model was developed, based on the continuum damage mechanics, in order to represent the behavior of the interface finite elements. This model is able to simulate the creation and propagation of cracks, as well as, the frictional effects in dependence on stress confinement on the interfaces. Furthermore, as the objective of this work aims to simulate the failure in the mortar joints, the brick elements are assumed as linear elastic material. Three node standard triangular finite element are used to represent the bricks. Several numerical models are carried out. Initially, basics tests are show in order to demonstrate the main characteristics of the proposed model subjected to tensile, compression and shear loads. Subsequently, masonry structures are subjected to static loads are analyzed and the results compared with the experimental responses in order to validate the proposed model. This technique proved to be very promising for the simulation of failure onset and propagation in mortar joints of masonry structures.
