A Study on the seismic performance of Butsuden and Hatto of Kenchoji Temple.

在1923年关东大地震中，武竹寺与武藤寺呈现出明显不同的断裂模式。但突然间，他完全倒下了。然而，哈托受到了轻微的损坏。本文对这些建筑的抗震性能进行了分析。一开始，对这些建筑的基本尺寸进行了调查。然后对这些建筑物中最有效的抗震构件柱-努基节点进行了测试。提出了柱-铰节点刚度和强度的估计方法。根据柱的稳定强度和墙体的货架强度估算了建筑物的总强度。从估算结果来看，与Hatto相比，Butsuden的潜在基底剪切系数较大。结果与事实不符。通过研究，提出了传统建筑抗震性能的评估方法。

Butsuden and Hatto of Kenchoji Temple showed apparently different broken mode through 1923 Kanto Earthquake. Butsuden was completely fallen down. However, Hatto was slightly damaged. In this study, the reason of the seismic performance of those buildings are investigated.At the beginning, the basic dimensions of those buildings were surveyed. Then column-nuki joints, which are the most effective seismic elements of those buildings, were tested. And the estimation method of the rigidity ant strength of column-nuki joints were proposed. Total strength of the buildings were estimated from the strength of stability of column and the racking strength of walls. From the estimation, the potential base-shear coefficient of Butsuden was rather large compared with Hatto. The result was different from the facts.Through the study, we proposed the estimation method of the seismic performance of traditional buildings.
