A Large-Scale Seismic Test (LSST) Program has been conducted at Hualien, Taiwan, (Tang et al., 1991) to obtain earthquake-induced soil-structure interaction (SSI) data in a stiff soil site environment. Forced vibration tests of the Hualien l/4-scale containment SSI test model were conducted in October, 1992 before backfill (without embedment) and in February, 1993 after backfill (with embedment) for the purpose of defining basic dynamic characteristics of the soil-structure system. Two horizontal excitations (NS, EW) were applied on the roof floor and on the basemat. Vertical excitation was applied on the basemat only. For the forced vibration tests of the model before backfill, resonance curves obtained showed two peaks for the NS and the EW excitaticn tests. It suggested that principal axes were different from NS and EW directions. Peak frequencies were obtained as 4.1 and 4.3 Hz for horizontal excitation before backfill and as 6.1 and 6.3 Hz for horizontal excitation after backfill. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
