- This work presents a formulation for non linear static analysis of rigid block models. The objective of this work is to develop a tool for the structural assessment of historical
masonry constructions. Rigid block models have proven to be effective for the analysis of both,
simplified models and macro models of unreinforced masonry elements and structures. This
modelling strategy captures well the proneness of masonry to localised cracking and is numerically efficient in the sense of requiring significantly less degrees of freedom compared to finite element models. The formulation uses numerical integration at interfaces and classical
non linear solution techniques. The use of this strategy in the analysis of a previously studied
masonry wall enlightens a number of its strengths and weaknesses. Work is in progress and
more elaborated constitutive models have to be included for both, tension and compression
behaviour. Also, we need to implement more sophisticated and efficient non linear analysis
techniques in order to improve the performance of the numerical tool.
