Summary

This paper discusses the benefits of recent enhancements introduced into a partitioned mesoscale modelling approach for brick-masonry structures. These include the use of master-slave coupling and hierarchic features which enable the improvement of efficiency, especially in the analysis of large masonry components. In particular, the new enhancements enable a reduction in the number of nodes at the parent structure and the use of multi-level partitions to distribute the computational load uniformly to the different processors used in parallel. Some numerical examples, including a comparative analysis on the elastic response of a large masonry wall and the nonlinear simulation of a realistic heterogeneous system under extreme loading, are presented to show the effectiveness of the proposed modelling strategy.
