1. Multiscale Modelling of Reinforced Concrete
Sammanfattning : Since concrete cracks at relatively low tensile stresses, the durability of reinforced concrete structures is highly influenced by its brittle nature. Cracks open up for ingress of harmful substances, e.g. chlorides, which in turn cause corrosion of the reinforcement. LÄS MER
2. Multiscale Modelling of Reinforced Concrete Structures
Sammanfattning : Concrete cracks at relatively low tensile stresses; cracks open up for ingress of harmful substances, negatively affecting the durability of reinforced concrete structures. Crack widths are thus limited in the design codes, and accurate predictions are needed, especially for large reinforced concrete structures such as bridges or nuclear reactor containment buildings.

3. Smart Energy Grids – Utilization of Space Heating Flexibility
Sammanfattning : Buildings are the largest energy-using sector in the world. Since the generation of energy is highly associated with greenhouse gas emissions, contributing to climate change, there is a large focus on reducing energy use in buildings. LÄS MER
4. 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.

5. Design for 3D Concrete Printing : Optimisation Through Integrated Workflows
Sammanfattning : The transition from conventional cast concrete to 3D Concrete Printing (3DCP) marks a paradigm shift by directly depositing fresh concrete layer upon layer according to a digital model without the need for a formwork. This technology offers the possibility of achieving innovative and complex geometries in an automated process. LÄS MER
