Abstract
The special and outstanding characteristics of ultra-high-performance concrete (UHPC) require the development of a multiaxial mechanical model for numerical investigations. With the three phases model it is possible to describe the behaviour of concrete from extremely brittle to more ductile using the characteristic development of the principal meridians, in particular the compressive meridian of the fracture surface. Furthermore, the anisotropic damage due to fatigue is considered in the principal-stress-area by different grades of damage in relation to the tensile and the compressive meridian. In experimental investigations, the necessary parameters are determined to calibrate the three phases model for UHPC by specifying the principal meridians for static loading. In further dynamic investigations the parameters for an anisotropic damage model are determined for fatigue loading.
