Full-Scale Dynamic Experimental Inspection of Fundamental Techniques Creating Near Future Type of Traditional Wooden Construction Sustainable to Earthquakes.

(1)为创造一种可承受任何地震的近未来型传统木结构建筑，确立了以下基本原则：1)利用木结构原有的吸振、隔振和控制机制；2)将一些现代简单技术应用于建筑中；3)使这些抗震机制发挥高效作用。(2)从墙体、连接、框架、基础的材料和构造等方面，设计并实现了几种与上述原则相适应的基本构造技术。(3)这些基本技术的代表有：圆筒形贴面材、改良土墙加木格、厚杉木板木墙、胶粘剂木榫缝、改良木连接的骨架框架、不连接支撑上部结构的石埋梁基础体系。这些都是日本传统建筑技术和智慧的结晶。它们的有效性和实用性是通过构件标本和全尺寸模型屋的静态测试来检验的，这两种测试都包括了其中的一种或两种技术。(4)在前人各项研究成果的基础上，构建了“土墙体系”和“杉木板墙体系”两种三维单元框架，并在研究所的振动台上进行了试验。最后研究了这些壁系的基本动力特性。因此，通过三维框架和全尺寸建筑的试验，令人满意地证实了所设计的基本技术积累效果的有效性和实用性

(1)The following fundamental principle was set up for creating a near future type of traditional wooden construction sustainable to any earthquake: 1) to utilize the vibration absorbing, isolating, and controlling mechanisms which exist originally in wooden structures, 2) to apply some kinds of modern simple technique to the construction, and thus, 3) to produce high efficient function of those resistant mechanisms.(2)Several elementary basic techniques to build structures, suitable to the above-mentioned principle, were devised and realized as for materials and constructions of wall, connection, frame, and foundation.(3)The representatives of such basic techniques are cylindrical Laminated Veneer Lumber, improved soil wall with wood lattice, wooden wall made of thick Sugi plates, wooden tenon joint using adhesive, skeleton frame with improved wooden connections, and stone and buried girder foundation system supporting upper-structure without connecting. All of them are resulted from Japanese traditional construction skills and wisdoms. And their validity and usefulness were examined through static tests of componential specimens and a full-scale model house, both of which included each or couple of those techniques.(4)Based on the various results of the previous study, two types of three dimensional unit frame, designated as 'soil wall and Sugi wood plate wall systems', were built and tested on the shaking table in the Institute. The fundamental dynamic characteristics of these wall systems were finally investigated. Thus, the validity and usefulness for the effects of accumulating the devised elementary techniques were satisfactorily confirmed through both tests of three dimensional frames and a full-scale building
