A Simple Method for Dynamic Time History Analysis Based on Equivalent Linearization
For complex sites,one-dimensional equivalent linearization can not reflect the terrain characteristics of the site and the nonlinear characteristics of the soil.In this case,two-dimensional linear elastic analysis is needed.In this paper,a new method is proposed for the parameter value of soil in two-dimensional linear elastic analysis.In order to verify the applicability of the proposed method for two-dimensional complex site conditions,one-dimensional frequency domain,one-dimensional time domain,and two-dimensional time domain models were established based on multiple boreholes and real site conditions in Odawara,Japan.The results verified the feasibility of the proposed method under two-dimensional complex site conditions.
