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 sha king table tests performed on a house built with th ree-leaf stone masonry in scale 2:3. The masonry properties were simulated using a continuum damage behaviour m del, [Faria et al., 1998], calibrated based on the resul ts of shear-compression tests, [Mazzon, 2010]. The model properties and boundary conditions of the house wer e fu ther verified with the dynamic identification tests performed on the house during the experimental camp aign. The applied macro-modelling strategy using a nonlinear continuum damage behaviour model was capable of r alistically simulating the behaviour of the m odel house under dynamic loads and more particularly the accumulative development of the damage in the stru ctu e and the corresponding crack pattern, showing howeve r limitations when trying to reproduce phenomena as the rocking behaviour of the house which induce high di splacements.
