The Effect of Seismic Response Characteristics of Subsurface Ground to Damage of Low-rise RC Building in the Iwate-Miyagi Nairiku Earthquake in 2008

Abstract

This paper discusses the difference of the damage level of the three schoolhouses in the vicinity of the epicenter of the 2008 Iwate-Miyagi Nairiku Earthquake with respect to ground response characteristics. We conducted microtremor measurements and aftershock observation at the site of Kaminome. One-dimensional equivalent linear analysis of the ground and three-dimensional seismic response analysis of the schoolhouse indicate that damage level of the schoolhouse of Kaminome meets good agreement with phenomenon considering non-linearity of the fill.
