<p> Level 4 of the long-period pulse ground motion was observed, for the first time in Japan, when the Kumamoto Earthquake hit Nishihara Village on April 16, 2016. Long-period ground motion is ground movement during an earthquake with a period longer than 1 second and instantaneously generates large acceleration. It may cause different behavior of furniture or buildings from past well-known damage situations.</p><p> This paper has investigated high-rise building location around Nagamachi-Rifu Fault Zone in Sendai City, one of the long-period ground motion anticipated faults in Japan at first, and analyzed overturning risk furniture in an office due to the long-period pulse ground motion using simulation and clarified following things.</p><p> 1. There are 37 high-rise buildings in the central district of Sendai City, which is exposed to Nagamachi-Rifu Fault Zone and 32 buildings (86%) are located within 3km from Nagamachi-Rifu Fault. Although most of them are located on the terrace surface, four buildings are built on the alluvial lowland.</p><p> 2. The total kinetic energy in case of island layout is the largest, and the energy produced by the 2011 Great East Japan Earthquake is 2.9 times larger than that produced by the 2016 Kumamoto Earthquake. In the case of the 2011 earthquake, the total kinetic energy with the 20-story building is 1.7 times larger than that with the lower building.</p><p> 3. Fixing furniture is the most efficient for the lower building hit by the 2016 Kumamoto Earthquake and it reduced the total kinetic energy to one third.</p><p> 4. In the comparative study of time history of the total kinetic energy, seismic movement was amplified in the 20-story building by the 2011 Great East Japan Earthquake though the movement was not so different between the lower building and the 20-story building in the case of the 2016 Kumamoto Earthquake. The peak of the total kinetic energy of furniture by the long-period pulse, namely the 2016 Kumamoto Earthquake, appears about 70 seconds earlier than the case of the 2011 earthquake.</p><p> 5. The maximum kinetic energy was observed in printer, heavy desks, and heavy cabinets in the simulation for 115 furniture items in the office.</p><p> 6. Overturning risk of furniture is different according to the layout of furniture in office room, and 卍-shaped pattern was the lowest among the prepared layouts in the research. It means that consideration of layout of furniture is one of the important factors to reduce human injury in the area when the long-period pulse ground motion is anticipated.</p>
