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. This paper has 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.
