Fields of research
The research of the Chair of Structural Concrete focuses on the following topics:
- Design and construction with ultra-high performance concrete (UHPC),
- Shear bearing behaviour of reinforced concrete members,
- Mechanics of fibre reinforced concrete (FRC),
- Retrofitting of reinforced and prestressed concrete structures in building and bridge construction,
- Innovative facade constructions,
- Serviceability of reinforced concrete structures.
The Chair of Structural Concrete is also involved in the Institute for Advanced Materials and Structures (FiBB) at the University of Siegen. There, it is working interdisciplinary within the School of Science and Technology as well as with other research teams and with the local building industry in the field of research, assessment and development of sustainable building materials and structures.
Current research projects
Current research projects deal with the following questions:
- Rotation capacity of plastic hinges in mixed reinforced UHPC flexural members
- Deriving the design value of the post-cracking tensile strength for ultra-high performance fibre-reinforced concrete taking into account the size effect on the scatter
- Shear bearing behaviour of slender reinforced concrete members without shear reinforcement with a low ratio of longitudinal reinforcement
- Inclination of cracks and bearing behaviour of prestressed UHPFRC girders subjected to shear
