文摘
- •
A multi-modal parametric evolutionary Kanai–Tajimi ground motion model is formulated.
- •
Developed parametric forms efficiently model highly non-stationary characteristics.
- •
The evolutionary features of a selected NGA database are stochastically quantified.
- •
The natural variability of associated ground motions is effectively characterized.
- •
The Spectral Representation Method supports the simulation of sample ground motions.
