1. A theory of bond applied to overlapped tensile reinforcement splices for deformed bars
Sammanfattning : A bond theory for deformed reinforcing bars in concrete is elaborated taking into account different stages in development of final rupture occurring as splitting or pull-out. The concrete cover splitting resistance is modelled for a thick-walled concrete ring in elastic and plastic stages. Different final possible failure modes are analysed. LÄS MER
2. Application of Fracture Mechanics to Concrete Bridges. Finite element analyses and experiments
Sammanfattning : Material models based on fracture mechanics together with non-linear finite element analyses have been used in combination with experiments to study the behaviour of reinforced concrete bridges. The work covers two aspects of interest in the design of concrete bridges.* The shear behaviour was studied in full-scale tests on two highway bridges. LÄS MER
3. Three-Dimensional Modelling of Bond in Reinforced Concrete Theoretical Model, Experiments and Applications
Sammanfattning : The bond mechanism between deformed bars and concrete is known to be influenced by multiple parameters, such as the strength of the surrounding structure, the occurrence of splitting cracks in the concrete and the yielding of the reinforcement. However, when reinforced concrete structures are analysed using the finite element method, it is quite common to assume that the bond stress depends solely on the slip. LÄS MER
4. Bond and Anchorage of Ribbed Bars in High-Strength Concrete
Sammanfattning : For structural utilisation of high-strength concrete, a good understanding of the bond and anchorage behaviours of ribbed bars in this specific material is essential. The research project aims to increase the knowledge of bond and anchorage behaviours of ribbed bars in high-strength concrete. LÄS MER
