- •
We propose a new EMD-ELM method to achieve multi-step prediction of ground motions.
- •
Acceleration time histories are decomposed into several IMFs by EMD.
- •
The ELM method is then utilized to predict the IMF components.
- •
Seismic responses of SDOF systems are also predicted with satisfactory accuracy.
