In the first stage, we developed stressed-skin wooden panels. Stressed-skin semi-monocock structures are often used for the light structures such as aircraft airframe components. In these structures, the stresses are carried not only by the framing members but also by the surface membrane. There has recently been increasing use of moment resisting glulam timber joints in building structures. However, these joints require relatively large cross-sections because the moment resistance is carried by only the linear elements. This is not only uneconomical but also unattractive. Bending experiments on panel joints were carried out. We have proposed moment resisting timber joints using stressed-skin effect. It has also presented equations for estimating the rotational rigidity and the maximum strength of the joints, and demonstrated their prediction capability with sufficient accuracy. It has been shown that a frame with a smaller cross-section than that of only rib members is achievable with this joint.In the second stage, we developed steel plate and sugi glulam timber structural members. Massive amount of Japanese cedar trees planted in Japan in 1950's are recently ready to be cut for usage, and various techniques utilizing such domestic cedar are required. However, for cedar timber has less stiffness and strength than Douglas fir, combination with steel to provide composite members will be one of the effective methods to expand the structural variations. Thin steel plate is sandwiched between two cedar glulams using shear-ring connectors and bolts. This study is aimed at developing this compoiste member.Axial compression tests and bending tests were conducted to determine the compression and bending characteristics.We proposed equations for estimating the strength and buckling mode, and demonstrated their prediction capability with sufficient accuracy.

在第一阶段，我们开发了应力蒙皮木板。应力蒙皮半单翼结构常用于飞机机体等轻型结构。在这些结构中，应力不仅由框架构件承载，而且由表面膜承载。最近，在建筑结构中越来越多地使用抗弯矩胶合木木材接头。然而，这些接头需要相对较大的横截面，因为力矩阻力仅由线性元件承载。这不仅不经济，而且没有吸引力。进行了板节点的弯曲试验。我们提出了利用应力表皮效应的抗弯木节点。它还提出了用于估计接头的旋转刚度和最大强度的方程，并以足够的精度证明了它们的预测能力。通过这种连接，可以实现比仅使用肋材的框架截面更小的框架。第二阶段，开发了钢板和杉胶合木结构构件。20世纪50年代在日本种植的大量日本雪松树最近准备被砍伐以供使用，并且需要利用这种国产雪松的各种技术。然而，由于雪松木材的刚度和强度都低于道格拉斯冷杉，与钢组合提供组合构件将是扩大结构变化的有效方法之一。薄钢板夹在两个雪松胶合板之间使用剪切环连接器和螺栓。本研究针对此复合构件进行轴压与弯曲试验，以确定其受压与弯曲特性，并提出强度与屈曲模式之估算公式，并验证其预测能力，其精度相当。
