Outline of Final Research Achievements

This research was conducted focusing on a braced shear wall installed in wooden houses build by the Post-and-beam construction system. Firstly, static shear loading tests on braced shear walls with three types of brace fastener and three wall length, namely 910 mm, 1365 mm and 1820mm were performed to understand the failure modes and the shear force-story displacement relationships. After that, static incremental analysis of the braced shear walls was conducted, and it was found that the incremental analysis model is adequate for estimating the shear force-story displacement relationships. It was also confirmed that the analysis model is valid for estimating the shear force-story displacement of a knee braced shear wall and a K-shaped brace shear wall. Additionally, trial experiment to examine the design method for the connection between the end of the brace and the frame was conducted to have useful knowledge.
