Calibration of a material behavior model for the simulation of multi-leaf stone masonry structures: Experimental case study application.

This paper presents the numerical simulation of shaking table tests performed on a house built with three-leaf stone masonry in scale 2:3. The masonry properties were simulated using a continuum damage behaviour model, [Faria et al., 1998], calibrated based on the results of shear-compression tests, [Mazzon, 2010]. The model properties and boundary conditions of the house were further verified with the dynamic identification tests performed on the house during the experimental campaign. The applied macro-modelling strategy using a nonlinear continuum damage behaviour model was capable of realistically simulating the behaviour of the model house under dynamic loads and more particularly the accumulative development of the damage in the structure and the corresponding crack pattern, showing however limitations when trying to reproduce phenomena as the rocking behaviour of the house which induce high displacements.
