项目摘要

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.

本研究的目的是开发抗震和加固设计方法，赋予传统木结构建筑高抗震性能，开发新的加固结构构件，并利用保护和增强文化遗产木结构建筑，如京町屋、神社和1.木结构建筑抗震性能评价方法的开发利用E-defense对京町屋和传统木结构建筑进行了振动台试验，验证了传统木结构建筑的抗震性能评价方法。通过对 2007 年能登阪东地震和 2007 年新泻县中越大地震中受损的木结构建筑进行勘察，对传统房屋和寺庙的抗震性能进行了评估。2 木构件的结构劣化诊断木构件的结构劣化诊断是通过调查木构件的结构劣化来进行的。木材构件和电子……建立了耐久性检查方法，对因腐烂和白蚁而损坏的房屋进行了劣化诊断。通过2007年能登阪东地震的勘察，探讨了劣化对抗震性能的影响。3．抗震设计方法的发展基于简单的“响应极限能力分析”方法来评价抗震性能。 2007年6月，《建筑标准法》的修订提出，对传统木结构建筑的抗震设计造成了严重的社会困扰。重新考虑了基于响应极限能力分析的设计方法，研究了柱的滑移和水平框架的变形，并将抗震设计方法付诸实际应用4．开发了泥墙和阶梯框架，并通过振动台试验验证了这些构件的加固效果，并在房屋和神社、寺庙等大型建筑中得到实际应用。 5．通过对现有寺庙的抗震性能进行评估和研究抗震加固方法，开发出抗震加固方法并投入实际应用。该方法是有用的，可用于文化遗产和历史木结构建筑的加固。神社、寺庙等历史悠久的木结构建筑较少。
