The purpose of this study is to develop the new seismic strengthening method of existing wooden houses. In this study, the fiber reinforced plastics (FRP) are used as the reinforcement material. This FRP hardens by irradiating the ultraviolet ray. In this study, we develop a good workability seismic strengthening method of existing wooden houses by using this FRP sheet. As a result, we were able to develop the new reinforcement design for the braced frame structural wall of the element ultimate strength (the wall ultimate strength factor) as over 4.0(kN/m) which was target value in this study.
