项目摘要

1)Two programs for automatically calculating wooden truss members were developed. One is a Japanese-Basic program and another included the nailing method on plywood gusset plates conecting the members. To ascertain practical accuracy of the calculation ,full-scale test was carried out. In this,test,it revealed that the gusset plates nailed with CN50 nails driven from the two sides had almost equal performance of those with CN75 nails driven from theone side and clinched.2)Gable frames constructed with tapered wooden members conected using three Kinds of fingerjoint methods were tested under vertical loads. Gable frames in which two members were simply fingerjointed at the haunch were the weakest in all, and the ones stiffened with a fillet at the inside of the haunch or used the insert between the two members were about 30 percent in the stiffness and about 40 percent higher than those of the frames simply fingerjointed.3)The method of predicting deformations of gable frames jointsd with nailed-plywood gusset plates developed using a stepwise linear analysis. This method is very useful for various kinds of nail arrangement.4)For effective use of small scale coniferous logs, I-beams consisting of the franfe of sawed lumber or LVL and the wed of edgeglued two-ply lumber glued at right angle each other and arranged 45 degree to the beam axis or fiberboard were designed and tested. From the test, it may be said that a balance of the strength of materials for the frange and the web.

1)编制了两个木桁架杆件的自动计算程序。一个是日本的基本程序，另一个包括钉在胶合板节点板连接成员的方法。为了确定计算的实际精度，进行了全尺寸试验。试验结果表明，采用CN 50钉双面钉入的节点板与采用CN 75钉单面钉入的节点板性能相当。2）对采用三种指接方式连接的楔形木构件进行了山形墙框架的竖向荷载试验。两个构件在臀部简单地指接的山形墙框架是所有框架中最弱的，在拱腹内侧加筋或在两构件之间加嵌件的框架，其刚度约为30%，比简单指接的框架提高约40%。胶合板节点板开发使用逐步线性分析。4）为有效利用小型针叶材原木，设计并试验了由锯材或单板层积材（LVL）的梁端与胶合板的梁端组成的工字梁，工字梁与梁轴线或纤维板成45 °角，两层胶合板的梁端相互胶合，两层胶合板的梁端相互垂直。从试验来看，可以说是一种平衡了材料强度的卷筒纸和卷筒纸。
