Concrete Structures

The structural concrete research group focuses on the load carrying and deformation capacity of concrete structures. This involves traditional concrete structures, innovative concrete structures and the assessment of the structural safety of existing structures. The group have a special focus on developing design models and assessment methods that can be used in practice. 

This often requires both experimental and theoretical research in order to develop the sufficient evidence of the developed models. The theoretical formulations are often based on the plasticity theory. The experimental research is conducted in the Section’s structural laboratory, which is equipped with state-of-the-art equipment for experimental research on concrete structures. 

The following projects are examples of research projects from the structural concrete group that are now applied in practice:

A mechanical model for calculation of the combined bending and tensile capacity of so-called U-bar loop connections. Said connections are used to ensure structural continuity between precast deck slabs of steel-concrete composite bridges. The model is now implemented in the final draft for the new European Standard for Concrete Structures, Eurocode 2. Furthermore, the model has already formed the basis for design of bridge deck connections in practice. See publication here

A mechanical model for calculation of the shear capacity of looped wire rope connections between precast concrete wall elements. The model is simplified and formulated in a Design Bulletin that forms the basis for design of such connections in Denmark. See publication here
