Reinforced Concrete
Empower your vision for sustainable concrete structures
Ultimate strength based on optimized design
Sustainable analysis and design of reinforced concrete structures, in conjunction with the limitations in material sources, such as cement and steel, forces engineers to optimize their design based on the ultimate strength of materials.
High profile structures such as dams and nuclear facilities, place an extreme level of importance on their serviceability state. Infrastructure constructions, such as bridges and high-rise buildings are additionally state-of-the-art with regards to architectural design, whilst still complying with safety and serviceability restrictions.
The complexity and importance of analysis, prediction of service, and possible failure mechanisms provide the argument for a powerful and capable software solution in order to simulate all aspects of materials models, and combinations of a wide range of loading conditions. The extensive features, and analysis capabilities of DIANA ensure that it is outstanding in this field, structures are analyzed, or even used for digital twin simulation, to avoid any interruption in the production of value driven structures, in both cost and safety.
Advancement in prediction of concrete failure mechanisms
Trusted simulation platform for concrete material models.
Accurately analyse the damage development and failure of reinforced concrete structures considering the different material characteristics of steel (i.e. rebar, fiber). DIANA’s reinforced concrete models are based on the exact geometry definition of reinforcements and concrete. It facilitates the explicit description of material failure of the steel reinforcements, the concrete and the bond-slip connection between both.
With DIANA you can perform integral failure analyses of structures, taking into account construction phases and loading history, including heat loadings, stresses from the concrete hardening, soil-structure interaction, dynamic loadings and changing material behavior over time.
At material level, it is possible to consider the heterogeneity of concrete, as well as introducing fiber materials in order to simulate fiber reinforced material models.
