Calculation of reinforcement to concrete adhesion in reinforced concrete elements
Abstract A model and method for calculating of reinforcement to concrete adhesion in reinforced concrete elements have been developed. The basic parameters by means of which it is possible to control interaction of reinforcement with concrete at any stage of a reinforced concrete element deformation are defined.

Diagnostics of Concrete and Steel in Elements of an Historic Reinforced Concrete Structure [PDF]
Existing buildings, especially historical buildings, require periodic or situational diagnostic tests. If a building is in use, advanced non-destructive or semi-destructive methods should be used. In the diagnosis of reinforced concrete structures, tests allowing to assess the condition of the reinforcement and concrete cover are particularly important.

Bond-Slip in Reinforced Concrete Elements [PDF]
A model for fiber reinforced composites that takes into account the fiber slipping is presented in this paper and applied to the analysis of reinforced concrete elements. The model is formulated within the framework of the plasticity theory and the mixtures theory, considering two phases corresponding to the matrix (concrete) and the fibers ...

A discrete element model for reinforced concrete [PDF]
AbstractReinforced concrete structures are built all over the world. The development of cracks is an unavoidable appearance, based on the interaction of the concrete and the reinforcement. The crack pattern can have an significant influence at the ageing of the structure.
