지진시험용 Hualien 대형구조물의 선형 지진응답해석 Linear Earthquake Response for the Hualien Large-Seismic Test Structure

This paper presents the earthquake response analysis results on the Large-Scale Seismic Test (LSST) structure which was built at Hualien in Taiwan. The seismic analysis is carried out using a computer code KIESSI, which has been developed based on the three-dimensional axisymmetric finite element method incorporating infinite elements for the far field soil region. The soil and structural properties obtained from the pest-correlation study of the forced vibration tests (FVT) as well as the unified model that was made from the insitu tests for soil and experiments for concrete specimens, is utilized to predict seismic responses. The ground accelerations recorded at a site 56.5m from the test structure are used as control motions. In general, the predicted responses using the FVT-correlated model show better agreements with the measured responses than those using the unified model. However, the damping appears to be underestimated for the rocking motion in the present analysis model. Comparisons of transfer functions between analysis results and measured data show that the nonlinearity in the soil medium near the structure can be significant in spite of the small magnitude of the earthquake excitation.
