摘要

Masonry is a composite material that can be defined as a materialincorporating a visible internal structure and having a low strength in tension. The lattercharacteristic has shaped most civil engineering structures up to the advent of reinforcedconcrete and iron/steel. Masonry is also present in most of our cultural heritagebuildings, which are part of our identity and represent a key attractor for tourism, amajor economical asset of Europe with 10% of the GDP. The paper will address differentchallenges: micro-modelling and homogenization techniques, which represent both apopular and active field on masonry research; dynamics and earthquake engineering,which remain far from being understood and challenge our modelling capacities. Thepresentation also addresses dynamic identification and inverse problems, or the art of amodelling engineer, as well as the engineering use of sophisticated numerical models,which provide significance to most of the problems addressed before.
