Concrete Structures
As part of the wind energy research at the Institute for Lightweight Structures and Conceptual Design (ILEK) of Stuttgart University research and development work is conducted for the design of structurally optimized towers for offshore wind energy converters. The towers consist of precast segments made out of ultra high performance concrete (UHPC) which are prestressed with external tendons.
Our Research
- Construction materials. Studies to investigate the material characteristics of ultra-high performance fibre-reinforced concrete (UHPFRC)
- Structural Analysis: Static and dynamic analysis (particularly determination of the resonance frequency) of the tower.
- Measurement of limit states, including:
- load bearing capacity
- second order analysis of
- deformations and internal forces
- measurements on cross-section level
- fatigue check
- serviceability
- Nodal points: Studies on the load bearing capacity of segmental joints
- Design of segmented construction:
- Unbonded prestressing
- Segmental joints
