The present work studies a partitioned approach for the numerical time integration of structures
with added damping devices in the context of wind-induced vibrations.
The coupled structure-damper interaction problem is partitioned in a structure and a damper
part and the interaction between both is treated by a Gauss-Seidel fixed-point iteration scheme.
The partitioning enables the modeling of the structure with an existing finite flement code,
whilst preserving a great deal of flexibility for the implementation of the added damper. It
is shown how the scheme can be extended to compute structures with multiple damping
devices. The accuracy and robustness of the partitioned approach is demonstrated for structures
with tuned mass dampers and viscous damping elements by comparing the results
obtained by the partitioned setup against monolithic solutions of the coupled problem.
Thereafter the partitioned approach is used to simulate structures with a semi-active tuned
mass damper featuring a controlled magneto-rheological damping element in order to show
how the partitioning makes it possible to include devices that are otherwise difficult to treat
within a given finite element setup.
Finally two methods, which merge the structure-damper interaction setup with a partitioned
fluid-structure interaction framework are discussed. Simulations are presented, which simulate
a coupled fluid-structure-damper interaction problem in a multiply partitioned way.
