Development of Analysis Model and Comparison of Seismic Analysis Responses with Test Results for an Isolated Test Structure for Liquid Reactor

액체금속로 면진 시험구조물의 해석모델링 개발 및 지진응답비교

The initial analysis frequencies of the isolated test structure for seismic excitation tests give quite higher values to the actual modal test results. This large difference was redulted from some uncertainties in analysis modeling of several connection regions between column and upper beam, cross bars of the isolated structure. A modified simple analysis model is developed representing the actual dynamic behaviors of the test model, and the seismic analysis responses of the simple model are compared with those of the seismic tests.
