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

1923年关东大地震中，建长寺的布津传和八藤表现出明显不同的破坏模式。武传彻底倒下了。不过，哈托受到了轻微的损伤。本文首先对这些建筑物的基本尺寸进行了测量，并对它们的抗震性能进行了分析。然后，对这些建筑中最有效的抗震构件--柱节点进行了试验研究。提出了柱-节点刚度和强度的估算方法。从柱的稳定强度和墙体的抗裂强度两个方面估算了建筑物的总强度。从估算结果来看，布津登的潜在基底剪切系数比哈托的大。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.
