Earthquake Response Analysis of A Large Scale Seismic Test Structure

대형지진시험구조물의 지진응답해석

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 post-correlation study of the forced vibration tests (FVT) are utilized to predict seismic responses. The ground accelerations recorded at a site 56.5 m from the test structure are used as control motions. It has been found that the predicted responses are reasonably compared with the observed responses.
