ESTIMATION OF SEISMIC INDOOR DAMAGE IN RESIDENTIAL BUILDINGS USING VULNERABILITY FUNCTIONS OF FURNITURE

Abstract

The functions to estimate overturning ratios of furniture in residential buildings are developed using indoor damage data during the 1995 Hyogo-ken Nambu Earthquake and results of analytical studies for overturning of rigid bodies. The functions are verified to match the indoor damage of tall buildings in Tokyo during the 2011 Off the Pacific Coast of Tohoku Earthquake. By using these functions, indoor damage in tall residential buildings in Tokyo is estimated during Nankai Trough earthquake and a large inland earthquake. The situation of indoor damage might be different depend on characteristic of seismic motions and buildings.
