Contract research
Earthquake engineering, structural dynamics incl. experimental structural dynamics, probabilistic investigations, innovative materials and load-bearing structures
Optical vibration measurement over long distances
Laser-based detection of vibration velocity and displacement in the micrometer range on supporting structures, even over long distances.
This enables us to measure where our conventional, highly sensitive accelerometers cannot be used or are very difficult to use.

Non-linear investigations of dynamic soil-structure interaction
The influence of dynamic soil-structure interaction is of crucial importance for the safety assessment of highly dynamically loaded structures. For example, induced vibrations due to an airplane impact are transmitted from the building envelope via the foundation and the floor into the building interior and can endanger important system components. These vibrations are not correctly recorded if the influences of radiation damping (soil-structure interaction) are neglected. Consideration of the floor using highly simplified methods, such as the use of static spring-damper elements, also leads to considerable inaccuracies. For a non-linear dynamic calculation, for example to include plasticization effects and damage in the structure, the soil and the building can be captured and analyzed in a finite element model.
