Research Abstract

This research report describes the results of a 3-year research, from the fiscal year 2003 to 2005. The research aims first to make an accurate ground motion distribution in Sendai area during the 1978 Miyagi-ken Oki earthquake, which was evaluated based on the recent knowledge of the earthquake and the geological circumstances ; second, to clarify the relation between ground motion characteristics and building damage features during the earthquake ; and third, to investigate the optimal seismic design and seismic retrofit of building structures considering ground motion characteristics affected by the geological circumstances, including surface layers and the deep underground structure.
In the fiscal year 2003, an earthquake observation network was constructed in order to evaluate observationally ground motion characteristics and buildings' behavior during earthquakes in different soil conditions. At the total number of 25 observation points small seismometers were installed (18 points … More thanks to the research fund of the Ministry of Infrastructure, Land and Transport). An optimal seismic design method and retrofit priority evaluation method of existing building structures were investigated.
In the fiscal years 2004 and 2005, the underground model constructed based on the recent geological information was verified by means of a simulation analysis using the observation records of the 2005/08/16 Miyagi-ken Oki earthquake and other earthquakes. After discussing the difference of ground motion characteristics of the 2005 earthquake and the 1978 earthquake, the ground motion distribution in Sendai area during the 1978 earthquake was revaluated. Building damage features observed at Nagamachi, Oroshimachi, and Kamisugi areas became consistent with the evaluated ground motion characteristics. Furthermore, optimal seismic design and retrofit of building structures considering the ground motion distribution were investigated. A seismic retrofit priority evaluation system of public buildings was developed for supporting municipal government officials in charge. Less
