Statics of Bodies Made of a Compressionally Rigid No Tension Material

  • Mario Como
Part of the Lecture Notes in Applied and Computational Mechanics book series (LNACM, volume 61)


The paper gives the basics of Statics of masonry bodies and extends to the continuum the compressionally rigid no tension model, usually applied to systems of arches and piers. Admissible stress, strains and admissible crack openings are defined together with some appropriate stress-strain inequalities. In this framework the virtual work equation is properly formulated by using a new simple approach that considers the new boundary of the body including the cracks surfaces. Then a condition on the loads, necessary and sufficient to the existence of the admissible equilibrium, is proven; this condition is very useful to deal with the collapse analysis. The paper ends pointing out some specific features of the behaviour of masonry structures, as the no existence of self stresses or the no existence of failures due to the occurrence of costraints settlements.
