Outline of Final Research Achievements

In this project, it was developed a scheme to synthesize a input motion that represents a set of possible ground motions based on data scientific methods. First, possible ground motions are divided into several clusters considering their effects on nonlinear structural response values. Second, In each cluster ground motions' characteristics are integrated to one artificial wave through the developed iterative learning procedure. These schemes were verified through numerical simulations.
