SOIL-STRUCTURE INTERACTION RESEARCH OF A LARCE-SCALE MODEL STRUCTURE AT HUALIEN, TAIWAN --- (PART 2) NUMERICAL SIMULATION OF FORCED VIBRATION TEST ---
|
´˜^i‰pjF
Predictive and correlative analyses of the forced vibration tests of the large-scale model structure resting on the gravelly layers before backfill were carried out as one of the analytical phases of an international Large-Scale Seismic Test (LSST) Program at Hualien, Taiwan. Predictions by axisymmetric FEM could be evaluated generally good, but it predicted resonant frequency (fo) about 9 % higher than the test and the resonant amplitude of the typical observation station (U¡,¡) about 33 % larger, for example, for the roof-horizontal excitation case. Correlative analyses followed to make up for the system frequency gap between prediction and test, utilizing comprehensive geotechnical site soil investigations performed along every construction stage, and consideration was made on them.
