摘要:
Timber pagodas have been built in Japan since 8th century AD. The construction system and technology has been imported from China through the Korean peninsula. There are 21 timber pagodas existing, built before 1850, the oldest date back to the 8th century. Although Japan is a strongly seismic prone country, literature survey show that there is no record of a timber pagoda which was totally damaged by earthquake. This is contradictory to the fact that many timber-brick pagodas were heavily damaged by the 2016Gorka earthquake in Kathmandu.

The structural characteristic of the traditional timber pagodas are described through structural experiments including micro tremor measurement, earthquake response monitoring and shaking table test. The characteristics are analyzed and discussed. Finally, based on the onsite investigation by the authors, structural performance of the timber –brick pagodas in Kathmandu are discussed in comparison with those in Japan.
