Outline of Final Research Achievements

Toward realization of large wooden buildings, wooden horizontal hybrid structure which involves stiff cores is focused on owing to the high seismic and fire safety. In this research, a new dynamics model representing the seismic behavior of horizontal hybrid structure was introduced, and evaluation formulae of seismic force distribution based on the theoretical analysis was proposed. In addition, shaking table test of one third scaled model and the numerical analyses were also conducted in order to discuss the dynamic behavior subjected to various intensity of earthquake motions. Finally, applicability of the proposed formulae was confirmed by comparison between test results and analysis results.
