Chair of Structural Analysis

We research and teach how civil structures deform, support and react - from everyday structures to modern, intelligent systems. The Chair of Structural Analysis combines theoretical principles, numerical simulations, experiments and data-based methods to open up new paths for the construction of the future.

Research profile

Data-driven modeling and identification

Our research focuses on the development of data-driven methods to represent the load-bearing behavior of structures more precisely and efficiently. This makes it possible to significantly accelerate particularly dynamic analyses and to reduce material consumption and workload.
 

The developed data-driven models are real-time capable and are applied in adaptive vibration control and structural monitoring. Using sensor data, they can be continuously updated to reflect the current condition of the structure, enabling more accurate vibration control and assessment.
 

Another field of application is real-time hybrid simulation, in which experiments are coupled with computational simulations to conduct dynamic tests on structural components.


We are also developing data-driven approaches for material modeling and parameter identification to gain new insights into nonlinear material behavior.
