Simplified but accurate numerical models have been created to replicate, by means of nonlinear static and nonlinear dynamic analyses, the experimental response of double-leaf stone masonry prototype buildings tested at Eucentre. The numerical models have been created following an existing equivalent frame macro-element approach and were calibrated to reproduce the damage pattern and the failure mechanisms activated during the shaking table tests, as well as the hysteretic behaviour of the strengthened prototypes at levels of acceleration similar to those of the shaking table tests. The numerical simulation showed a significant consistency of the nonlinear static and nonlinear dynamic analysis results with the experimental response of the prototype buildings.
