In the country designated as national treasures and cultural treasures, was built in most of the timber. These traditional wooden structure are state on degradation and deformation caused by deterioration, and it's about time that maintenance and preservation should take a deep interest.

So, this study choose unit member where many damages happen to structural members of wooden cultural property, and made 8 specimen of rectangular section of flexural member to understand the structural behavior and phase by reinforce damaged members with synthetic resin.
The results of the experiment, the most neutral axes of specimens are located at the opposite of the reinforced part. If the neutral axis moves to the reinforced part, the maximum strength is expected to be improved. And the compression is judged to be effective.
