Abstract:The ductility of High Performance Concrete (HPC) can develop both in tension and compression.
This aspect is evidenced in the present paper by measuring the mechanical response of normal
vibrated concrete (NC), self-compacting concrete (SC) and some HPCs cylindrical specimens
under uniaxial and triaxial compression. The post-peak behaviour of these specimens is defined
by a non-dimensional function that relates the inelastic displacement and the relative stress during
softening. Both for NC and SC, the increase of the fracture toughness with the confinement stress
is observed. Conversely, all the tested HPCs, even in absence of confinement, show practically the
same ductility measured in normal and self-compacting concretes with a confining pressure. Thus,
the presence of HPC in compressed columns is itself sufficient to create a sort of active distributed
