Outline of Final Research Achievements

The objective of this study is to propose a seismic reinforcement of traditional wooden houses with voids and large hanging walls. First, we evaluate aseismic performance of traditional wooden houses in Mimitsu, Miyazaki prefecture which have voids and skip floors based on the structural investigation. Next, we propose a maximum response deformation evaluation method of traditional wooden houses based on microtremor measurements. We also propose a simplified characterization method of pulse-like ground motions. Finally, we conduct static loading tests and simulation analyses of two traditional timber frame structures with large hanging walls; one is applied seismic reinforcement and the other is not, respectively.
