A new wood-framed construction based on the simplification of joints sorts.

1.研究目的：本计画的目的是提出一种新型的木结构建筑，并探讨其结构特性.研究结果：（1）施工原则：采用燕尾榫或燕尾榫与榫并用的方法施工。但是，应避免在一个节点（空间）处过度重复构件。(2)实际构造的预设：采用带搭接的燕尾榫连接，其长度大于构件宽度的一半，以加强连接。在节点处要复制的成员数设置为两个。在这些条件下，设计了平面（2.73x0.80x1.10（m））和实体（1.6x0.90x0.75（m））框架模型，实际上是由烘干的西部铁杉制成的。(3)机械性能说明：通过在水平方向上施加循环或斜坡载荷对上述模型进行测试。平面框架的刚度随柱数的增加而增加，柱数为2 ~ 4时，以及节点金属的使用而增加。实心框表示增殖率0.5-0.8/壁的值。半刚性结构分析的结果与试验结果吻合较好，这些结果已在与本项目相同的报告中发表。

1. Purpose of research : The purpose of this project is to present a new type of wood framed construction, and to investigate structural characteristics of the purposed construction.2. Obtained results : (1) Construction principle : A dovetail or both of it and a tenon is to be used for the construction. However, an excessive duplication of the members at one nodal point (space) is to be avoided. (2) Presetation of actual constructions : The dovetail joint with lap is adopted, and its length is longer than a half of the breadth of the members in order to strengthen the joint. The number of members to be duplicated at a nodal point isset to two. Under these conditions both the plane (2.73x0.80x1.10 (m)) and the solid (1.6x0.90x0.75 (m)) frame models were designed, and actually made of kiln-dried western hemlock. (3) Clarification of mechanical performances : The models above were tested by applying cyclic or ramped load in the horizontal direction. The stiffness of the plane frame was increased with the increase of number of columns two to four, and with the use of joint metals. The solid frames indicated the values of the multiplying rate 0.5-0.8/wall. The results of the application of the semi-rigid structural analysis to the models showed good agreements with the experimental.These results obtained are described in the report published under the same title as that of this project.
