An experimental and theoretical study of parameters of interaction between a repaired reinforced concrete structure and strengthening elements at cyclic and long-term loading. The issue is directly related to the short-term tests performed within the former VEGA – project 2/0143/12. The following topics will be solved within the project. An influence of rheological features on deformation and stress state of composite cross-sections of strengthened elements. An influence of a type of the contact repaired/strengthening element on resistance and serviceability. An investigation of a time evolution of the interaction of an element with GFRP sheets or with an overconcreted coupling slab, including a contact type. A failure processes analysis by evaluation of strain energy. A diagnostics and prediction of a failure state by a numerical modelling (ATENA 3D) and a comparison with selected experimental measurements. Generation of a results database with the focus on exploitability at optimisation of an bridge design.
