Abstract:
Discrete element models are a powerful tool for the analysis of masonry, given their
ability to represent the discontinuous nature of these structures, and to simulate the most common
deformation and failure modes. In particular, discrete elements allow the assessment of the seismic
behavior of masonry construction, using either pushover analysis or time domain dynamic analysis.
The fundamental concepts of discrete elements are concisely presented, stressing the issues related
to masonry modeling. Methods for generation of block models are discussed, with some examples
for the case of irregular stone masonry walls. A discrete element analysis of a shaking table test
performed on a traditional stone masonry house is discussed, as a demonstration of the capabilities
of these models. Practical application issues are examined, namely the computational requirements
for dynamic analysis.
