The topic of this research is the analysis of earthquake design of bridge structures using modal analysis. The aim of the research work is to answer the question of how to choose the necessary modal shapes to be considered in the modal analysis in order to minimize the running times while ensuring the accuracy of the calculation results. In addition, the research should also investigate different modelling options for substructures (considering substructure/pile weight / using only replacement springs, etc.) and determine the ideal solution. The evaluation of the examinations will be carried out mainly through the analysis of the resulting bearing reactions and the inoor forces of the piles and substructure.
