Summary
In this paper, the design sensitivity of dynamic characteristics of planar frames with viscoelastic (VE) dampers mounted on them is considered in detail. A family of classical rheological models is adopted to describe the VE damper behaviour. The dynamic characteristics of structures are determined as a solution to the appropriately defined quadratic or linear eigenvalue problem. The adjoint variable method is used to determine the above mentioned sensitivity. In particular, the design sensitivity of the dynamic characteristics of the system with respect to damper's parameters is analyzed. Moreover, the results of typical calculations are presented and discussed.
