AB  - Response spectra are of fundamental importance in earthquake engineeringand represent a standard measure in seismic design for the assessment of structuralperformance. However, unlike Fourier spectral amplitudes, the relationship of responsespectral amplitudes to seismological source, path, and site characteristics is notimmediately obvious and might even be considered counterintuitive for high oscillatorfrequencies. The understanding of this relationship is nevertheless important forseismic-hazard analysis. The purpose of the present study is to comprehensively characterizethe variation of response spectral amplitudes due to perturbations of the causativeseismological parameters. This is done by calculating the absolute parametersensitivities (sensitivity coefficients) defined as the partial derivatives of the modeloutput with respect to its input parameters. To derive sensitivities, we apply algorithmicdifferentiation (AD). This powerful approach is extensively used for sensitivity analysisof complex models in meteorology or aerodynamics. To the best of our knowledge, ADhas not been explored yet in the seismic-hazard context. Within the present study, ADwas successfully implemented for a proven and extensively applied simulation programfor response spectra (Stochastic Method SIMulation [SMSIM]) using the TAPENADEAD tool. We assess the effects and importance of input parameter perturbations on theshape of response spectra for different regional stochastic models in a quantitative way.Additionally, we perform sensitivity analysis regarding adjustment issues of groundmotionprediction equations.
