A traditional wooden five-storied pagoda was structurally designed on the basis of the performance design concept against wind, earthquake and snow loads. The present paper describes the design loads evaluation, the non-linear structural analyses, and the strengthening techniques. The static wind and the earthquake response analyses were successfully performed in consideration of the key mechanisms such as the semi-rigidity at the column-beam joints. The calculated story drifts showed that the strengthened structure would be safe against the design loads for the return period of 200 years.
