| Research Abstract |
Following the 1995 Hyogoken-nanbu earthquake, Japan Society of Civil Engineers issued"Proposal on earthquake resistance for civil engineering structures". Among others, Level2 earthquake motion of extreme intensity to be expected in the so-called near-field was requested to be taken into consideration in the future seismic design. However, in the current state of knowledge and technology, there are many difficulties in evaluation of Level2 motions generated from active inland faults. Based on this background, we have tried to make any contribution to facilitate the evaluation taking into account effects of source, path and local geology. As a result of our effort, conception and methodology for the evaluation are presented, together with case histories of Bell Houses' jumping caused by near-fieldm otion.
