| Abstract: |
| The appropriate determination of Rayleigh confficients for the damping matrix is significant for accurate analysis of soil layers with deep deposit.|H|i2|H|'i2|A|i2 was proposed to be the weighting coefficient of weighted least-squares method,which is widely used to obtain Rayleigh damping coefficients,to enhance computation accuracy of time-history analysis of seismic response of soil model.Dynamic response of a typical soil model with deep deposit,exciting by 28 typical seismic waves,was analyzed to verify the accuracy and applicability of the proposed method. |
