Study on seismic design and enhancement design of traditional wooden buildings in preparation for large earthquakes

本研究的目标是开发具有高抗震性能的传统木制建筑的抗震和增强设计方法，并开发用于加固的新结构构件，以及使用保护和增强文化遗产木制建筑，如京町屋，神社和寺庙。木结构抗震性能评价方法的发展，采用E-defense对京町屋和传统木结构进行了振动台试验。对传统木结构建筑抗震性能评价方法进行了验证。通过对2007年北韩东地震和2007年新竹中崎地震中受损木结构建筑的勘察，对传统房屋和寺庙的抗震性能进行了评价。木构件结构劣化诊断木构件结构劣化诊断是通过对木构件结构劣化进行研究，建立一套耐久性检测方法而发展起来的。2 .通过对2007年北阪神大地震的调查，探讨了因腐烂和白蚁而受损房屋的劣化诊断，以及劣化对抗震性能的影响。抗震设计方法的发展基于简单的“反应极限承载力分析”方法，提出了评价传统木结构抗震性能的抗震设计方法。《建筑标准法》于2007年6月修订。这一修订给传统木结构建筑的抗震设计带来了严重的社会困扰。重新考虑了基于响应极限承载力分析的抗震设计方法。对柱的滑移和水平框架的变形进行了研究。并将抗震设计方法应用于实际。抗震加固方法的发展作为适用于传统木结构建筑的抗震加固构件，干泥墙和梯架得到了发展。通过振动台试验验证了这些构件的加固效果。这些抗震加固构件在房屋和神社、寺庙等大型建筑中得到了实际应用。在保护和加固文化遗产和历史木结构建筑中的应用通过对一座现存寺庙的抗震性能评估和加固方法的研究，开发了抗震加固方法并将其投入实际应用。建议的方法是有用的，并可用于加强文化遗产和历史木制建筑，如神社和寺庙。少

The objectives of this study are to develop seismic and enhancement design methods endowing high seismic performance with traditional wooden buildings and to develop new structural members for reinforcement, and to use conservation and enhancement of cultural heritage wooden buildings such as Kyo-machiya houses, shrines and temples.1. Development of method for seismic performance evaluation of wooden framesShaking table tests of Kyo-machiya and traditional wooden frames using the E-defense were carried out. The evaluation method of seismic performance of traditional wooden buildings was verified. The seismic performance traditional houses and temples were evaluated by reconnaissances of damaged wooden buildings from the Noto Hanto Earthquake in 2007 and the Niigataken Chuetsu-oki Earthquake in 2007.2. Structural deterioration diagnosis of timber membersThe structural deterioration diagnosis of timber members is developed by investigating structural deterioration of timber members and e … More stablishing a inspection method of durability. The deterioration diagnosis of damaged houses from decay and termite were investigated from the reconnaissance of the Noto Hanto Earthquake in 2007, and the influence of deterioration to seismic performance was investigated.3. Development of seismic design methodsThe seismic design method based on a simple method "response-limit capacity analysis" to evaluate the seismic performance of traditional wooden buildings is proposed. The building standards law was revised in June, 2007. This revision caused serious social trouble on the seismic design of traditional wooden buildings. The seismic design method based the response-limit capacity analysis was reconsidered. The slipping of column and deformation of horizontal frame were investigated. And the seismic design method was put to practical use4. Development of seismic enhancement methodAs seismic reinforcement members applicable to traditional wooden buildings, dry mud-walls and laddery frames were developed. The reinforcement effect of these members were verified by shaking table tests. These seismic reinforcement members were applied in practical use for houses and large scale buildings such as shrine and temple.5. Application to conservation and enhancement of cultural heritage and historical wooden buildingsThe seismic enhancement method was developed and put to practical use by evaluating the seismic performance and investigating the seismic enhancement method for a existing temple.The proposed method is useful and is applied availably to the enhancement of cultural heritage and historical wooden buildings such as shrines and temples.
