چکیده
This study provides a comparison of results from dynamic centrifuge tests and finite element analysis model to confirm the behavior representative Korean stone pagoda cultural heritage structure against earthquakes. The indirect stiffness or physical state was estimated by measuring natural frequency masonry pagoda. actual measured be 4.5 Hz. It determined have lower than other pagodas similar size. For experiment, centrifugal separator test performed on 1/15 model. Data an earthquake record, Ofunato earthquake, were used, with various maximum acceleration levels ranging 0.069 g 0.424 g. In order accuracy model, compared modal When data obtained experiment PGA (peak ground acceleration) FEM complex using validated result compared, it found low average error rate 13%. shows that structural can predicted for structures method in future.
