Аннотация

The article focuses on seismic excitation models and methods for generating and processing seismic records. Synthetic accelerograms were developed using probabilistic and stochastic methods following Eurocode 8 standards. The study addresses the correction of baseline errors in accelerograms to ensure accurate velocity and displacement values. Fourier Transform methods are applied to analyze temporal responses.

A proposed model incorporates P and S waves with varying incidence angles and amplitudes to assess their effects on structures. The article also presents a method for calculating transfer functions and transitioning between time and frequency domains. The work enhances seismic analysis accuracy and contributes to safer structural design in earthquake-prone areas.
