Description
High-performance concretes are cementitious composites developed for particular structural or construction needs. They can include high-strength, fiber-reinforced and ultra-high-performance concretes. Those concrete types have different compositions and mechanical properties, leading to variable failure properties under given load scenarios. The focus of this work is to explore if diffuse and localized failure modes can be mathematically predicted taking as a basis the non-linear Performance Dependent Model (PDM), that has been proved to appropriately capture failure conditions for plain concretes of variable compressive strengths. The numerical results in terms of characteristic failure modes and critical directions are compared against experimental evidences.
