6. Anchorage of Corroded Reinforcement in Existing Concrete Structures: Experimental Study
Sammanfattning : The decrease in bond capacity and its relationship to the crack widths and patterns documented were studied for both the naturally corroded specimens tested in this study and artificial corrosion tests from the literature. A reduction of bond strength with increasingly maximal crack widths was observed in both types of tests. LÄS MER
7. Anchorage in Concrete Structures : Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors
Sammanfattning : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. LÄS MER
8. Externally unbonded post-tensioned CFRP tendons : a system solution
Sammanfattning : The introduction of Fibre Reinforced Polymers (FRP) to the civil engineering market in the late 1980s resulted in the emergence of a range of new tools for rehabilitating and strengthening concrete structures. Strengthening using FRPs is typically accomplished using non-prestressed externally bonded FRPs. LÄS MER
9. Flexural Strengthening of Reinforced Concrete Beams Using Externally Bonded CFRP--An Innovative Method for the Application of Prestressed CFRP Laminates
Sammanfattning : 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.

10. Structural Effects of Reinforcement Corrosion in Concrete Structures
Sammanfattning : Reinforcement corrosion is a common cause of deterioration in reinforced concrete.The corrosion mechanism involved and the consequent structural behaviour ofdeteriorated reinforced concrete members have been studied by several researchers. LÄS MER
