Outline of Final Research Achievements

The assessment system for falling standing statue made by clay and dry-lacquer by earthquake was developed. At first, it was confirmed a few cases that was adopt any anti-seismic measures for example seismic isolator. And it was found that the heel of some standing statues was clacked because of stress concentration when they were shaken. Then, higher accuracy method using extensive distinct element method (EDEM) was developed that was considered as a structure body. Furthermore, it was confirmed the seismic behavior of cray image by the vibration table examination.
