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

1. 研究目的：本项目的目的是呈现一种新型的木结构建筑，并研究目的建筑的结构特点。得到的结果：(1)施工原理：采用燕尾或同时使用燕尾和榫头进行施工。但是，要避免在一个节点（空间）上过多地重复成员。(2)实际结构说明：采用搭接燕尾接缝，其长度大于构件宽度的一半，以加强接缝。在一个节点上要复制的成员数设置为2。在这些条件下，设计了平面（2.73x0.80x1.10 (m)）和实心（1.6x0.90x0.75 (m)）框架模型，并实际使用窑干铁杉制成。(3)力学性能的澄清：以上模型均在水平方向上施加循环或斜坡荷载进行了试验。平面框架的刚度随着柱数的增加和节点金属的使用而增加。实体框架表示倍率为0.5-0.8/壁。模型的半刚性分析结果与试验结果吻合较好。这些结果在与本项目同名的报告中进行了描述。

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.
