| Abstract: |
In this study, we evaluated the seismic performance of existing temple, which is a traditional wooden structure, based on the field survey, 3D FEM analysis of unit frame in order to estimate the restoring force of main beam called Nuki, and calculation of response and limit strength. In the calculation results by the existing design code in Japan, the seismic performance evaluation of the structure became a significantly lower result, and the seismic diagnosis that is likely to collapse in a large earthquake was obtained. In conducting the parameter study of 3D FEM analysis, however, the strength evaluation of Nuki can be obtained a higher result than the design code. If the response and limit strength is recalculated based on these analytical results, the seismic evaluation of the entire structure is considerably improved. |
