Investigation of the influence of mechanical loading on the corrosion rate of reinforcing steel – Strain-induced corrosion crack test on structural samples
In the view of the safety and sustainability costs of maintaining our infrastructures, there is an urgent need to better understand the behaviour of materials under working conditions, i.e., environmental conditions and mechanical stress. The aim of the project is explaining the failure of reinforcing steel, which has occurred in several locations in water-locks. In these locations, and in addition to the presence of a cracked concrete, the steel rebars endure alternating mechanical loading that caused <More>
The influence of pile-driving induced vibrations on the hydration of early-age concrete regarding cast-in-place concrete pile groups
Concrete is a widely utilized construction material, owes its structural integrity to its mechanical strength. The strength development of concrete is possibly disturbed because of early age vibrations and these effects cannot be inspected visually for damage. The defects resulted from <More>
Automated data acquisition for life cycle management optimization using precast elements in the construction of massive waterways structures with coupling to BIM methodology
he objective of this research project is to develop a concept for coupling BIM methodology with automated data acquisition
to optimize the construction process and the life cycle management of precast elements in hydraulic engineering. The research project consists of two phases: In the first phase, a measurement and monitoring concept for the construction and service life phases of precast components will be developed. In the second phase <More>
Structural Health Monitoring (SHM)
The overarching goal of the SHM project is to develop new and innovative methods to monitor infrastructure buildings and to evaluate continuously their structural conditions. In this project, an interdisciplinary team consisting of engineers and mathematicians works together with industrial companies. <More>
Crack Widths in Reinforced Concrete Structures: Problems, Analysis and Perspectives for Ensuring Durability
A combination of desirable properties such as a high compressive strength, a broad availability of its raw materials and a superior cost efficiency make concrete the most widely used construction material in the world. However, due to its low tensile strength the formation of cracks from micro to macro scale due to load and load independent deformation caused by e.g., shrinkage, is unavoidable. Cracks can serve as pathways for aggressive chemical substances that can lead to a progressive deterioration of the cement stone as well as of the reinforcement, affecting the load capacity, service life and usability of concrete structures. <More>
