Verification of Earthquake Damage to Traditional Japanese Timber Structures, Considering the Deterioration of Joints

本研究旨在阐明传统木结构建筑的地震反应。日本传统木结构建筑的结构性能取决于节点的性能。木材的劣化尤其是节点处的劣化对整体结构的结构性能影响很大，但其量化方法尚未得到验证。本研究进行了(1)材料试验与联合试验，(2)联合模型的提出，(3)既有木结构的地震反应分析，(4)传统木结构的地震监测与微震测试，(5)分析与试验的对比。

This research aims to clarify the earthquake response of traditional timber architecture. The structural properties of traditional Japanese timber architecture rely on the performance of the joints. The deterioration of timber especially at the joint has a large influence on the structural property of total structure, but the quantification method has not been verified. In this research,(1) material test and joint test,(2) proposal of a joint model,(3) earthquake response analysis of existing timber architecture,(4) earthquake monitoring and micro tremor measurement of traditional timber architecture,(5) comparison of analysis and experiment, was operated.
