Correlation analysis for forced vibration test of the Haulien large scale seismic test program Original Research Article

The correlation analysis for forced vibration test of a 14 scale containment SSI test model constructed in Hualien, Taiwan, was carried out for the case of backfilled foundation. Prior to the correlation analysis, structural property was revised so that calculated fundamental frequency of fixed base condition was adjusted to that derived from test results. Correlation analysis was carried out by ‘Lattice Model’ which was able to estimate soil-structure interaction effects with embedment. The analysis results coincide well with test results and concluded that the mathematical soil-structure interaction model established by the correlation analysis is efficient to estimate a dynamic soil-structure interaction effect with embedment. This mathematical model will be applied as a basic model of simulation analysis for earthquake observation records.
