1. 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
2. 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
3. Effects of Steel Fibres on Cracking in Reinforced Concrete
Sammanfattning : ABSTRACTAlthough it is well known that fibre reinforcement acts as a crack arresting agent, there is still a need for deeper knowledge of the actual cracking behaviour, especially regarding cracks with widths smaller than 0.3mm. LÄS MER
4. Structural Behaviour of Deteriorated Concrete Structures
Sammanfattning : A growing concern for better assessment of existing concrete structures has revealed a need for improved understanding of the structural effects of deterioration. The two most common causes of deterioration in concrete structures are freezing of the concrete and corrosion of the reinforcement. LÄS MER
5. Experimental investigation of steel cables for rock reinforcement in hard rock
Sammanfattning : This thesis describes a detailed experimental investigation of the mechanical behaviour of fully grouted steel cables used for rock reinforcement in hard rock. An attempt is also made to explain the possible modes of deformation and cable failure, based on observations from the experiments. LÄS MER
