Discussion on weighted least-squares method for solving Rayleigh damping coefficients
摘要
Abstract
The appropriate determination of Rayleigh confficients for the damping matrix is significant for accurate analysis of soil layers with deep deposit . H 2i H′2i A 2i 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.关键词
