| Abstract | A solution scheme is presented for the determination of free-field ground motion, from
the measured accelarogram at a single point on the ground surface. It is appropriate to note
that this technique identifies all dominant seismic waves. Based on the shallow focus earthquake
mechanism a hypothesis is proposed to obtain the steady state correlation function. An efficient
numerical integration method for constructing the infinite element impedance matrix is devised,
which reduces the computational cost drastically. A numerical technique for the inverse Fourier
transform is presented and validated.
In order to demonstrate the capability of the scheme, which is proposed for the
determination of free-field ground motion an illustrative example is presented. In this example
soil medium is assumed as multi-layered visco-elastic half space. The proposed technique could
be easily extended for the entire soil-structure interaction analysis. |
