| Outline of Final Research Achievements |
The research aimed to push forward seismic diagnosis and retrofitting projects in Japanese timber houses, to provide design tool which visualize seismic diagnosis scores in coordinated system and each of performance advance caused by applied elements as a vector. Seismic retrofit would be efficient through an ideal combination of reducing dead load and applying extra rigidity of building frame. This logic was visualized as a design tool ready to be used by the designers.
The feasibility of the design tool has proven through elaborated testing went through 140 examples of real retrofit designs collected from practitioners, and even 12 examples out of them prove cost estimation testing. Basic data of seismic performances of popular seismic elements were collected and listed through the research. The logical proposal of the design tool is now getting into the application phase to be built into the BIM system to be used by practitioners.
