Ground Motion Time History Simulation for Seismic Response History Analysis
Frontiers in Earth Science, 2022 In the seismic design and analysis of important structures, ground motion time histories are generally required as the input for the conduction of seismic response history analysis. Taking a selected spectrum as the target, the approaches for generating spectral compatible time histories based on artificial or synthetic ground motion and real recorded ...
