1. FRP shear strengthening of reinforced concrete beams
Abstract : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).

2. Strengthening reinforced concrete structures with FRP composites
Abstract : Civil infrastructures made of reinforced concrete (RC) play an important role in the economic activities and services of society. However, signs of deterioration and functional deficiency are commonly found in existing RC structures. Thus, there is a great demand for upgrading the capacity and performance of existing concrete structures. READ MORE

3. Load-carrying capacity of a strengthened reinforced concrete bridge : Non-linear finite element modeling of a test to failure. Assessment of train load capacity of a two span railway trough bridge in Örnsköldsvik strengthened with bars of Carbon Fibre Reinforced Polymers (CFRP)
Abstract : To meet the future traffic demands there is a constant need of making the infrastructure moreeffective. This can be achieved by increasing the capacity and/or life length of traffic lines. READ MORE

4. Flexural Strengthening of Reinforced Concrete Beams Using Externally Bonded CFRP--An Innovative Method for the Application of Prestressed CFRP Laminates
Abstract : A large number of existing bridges in European countries are structurally deficient and functionally obsolete due to the deterioration of aging bridges and the lack of structural and geometric capacity to accommodate the increasing traffic volume and load levels. To meet the demand for holistic and effective strengthening techniques the SUREBRIDGE solution is proposed for the refurbishment of concrete bridges, which includes the technique of using prestressed carbon fiber reinforced polymer (CFRP) laminate as externally bonded reinforcement for flexural strengthening.

5. Numerical analysis of concrete elements strengthened with carbon fiber reinforced polymers
Abstract : Due to the growing number of ageing reinforced concrete structures such as buildings and bridges, there is an increasing interest in condition assessment and strengthening methods. Deterioration processes and demands for higher loads contribute to this interest. READ MORE
