Abstract
A specific simplified rigid element approach is proposed to model the elasticplastic
behaviour of masonry walls subjected to in-plane loadings. This proposal
originates from the consideration that the evaluation of seismic vulnerability
of masonry monuments requires peculiar procedures since their
responses to earthquakes often differ substantially from those of ordinary
buildings. In particular, the effective characterisation of the masonry material
requires a special attention because the global mechanical behaviour
of this composite material depends strongly on the different textures, as well
as on the elastic-plastic characteristics of the component materials. Numerical
analyses are made with the objective of evaluating the importance of
the micro-structure effects in the response of masonry walls with special
attenti
