Recently, medium large scale wooden buildings have became popular. Large rooms are often located in these buildings such as auditoriums, conference rooms and so on. In order to create these rooms, it is required to develop Stressed-Skin Panels (SSP) which support long span floor. The purpose of this study is to clarify the bending performance of SSPs. Bending performance of SSPs depends on tensile strength and stiffness of their flanges. For this reason, tensile tests of plywood used as flanges are conducted and plywood with the best properties are selected. After that, full size bending tests of SSPs are carried out to measure bending performance and the validity of the evaluation method was verified.
