This thesis deals with adjoint sensitivity analysis for structural transient problems. The numerical analysis is particularly impressive because of its efficient calculation of sensitivities according to several design parameters, which is of great advantage for certain applications in optimization. The design parameters mentioned above are, for example, mass, damping or stiffness parameters of the structure, which have a decisive influence on the dynamic system behavior. In this thesis a descriptive and structured derivation of two variants of the adjoint analysis is performed. Convergence studies allow the evaluation of the methods regarding the degree of time discretization. In order to enable an application of the analysis in structural dynamics, response functions relevant to construction practice are presented. On the one hand, it is shown how sensitivities of design parameters can be determined with respect to the energy dissipation of dynamic systems. On the other hand, concepts of mean values are studied, with the help of which the vibration responses of such systems can be characterized over a certain period of time. In order to demonstrate the practical suitability of adjoint
sensitivity analysis, it is applied in the optimization of dynamic vibration absorbers. For this purpose, problem-specific optimization criteria accessible to numerical optimization must be developed. The calculations are performed using the example of a steel chimney which is designed with a dynamic vibration absorber. Finally, the results are compared with analytical optimization criteria.
