Finite/discrete element models for assessment and repair of masonry structures

The predictive modelling of masonry structures represents a challenge due to their semidiscrete and composite nature. This paper presents an approach to modelling which considers the composite action of individual masonry components as an alternative to macro-modelling based on a homogenised continuum. A primary aim of the current research is to develop computational procedures for assessing the remnant strength of damaged masonry structures and to examine the efficiency of alternative repair strategies. Technical issues considered in the paper include the coupling of polygonal discrete elements for simulating the behaviour of masonry structures with circular discrete elements for representing geotechnical fill material. The approach adopted for parallel solution is also summarised.
