The Hyogo-ken Nanbu Earthquake, occurred on January 17, 1995, caused serious damage to the bridge structures. Loosening was observed in a few hanger cables of two Nielsen-Lohse bridges after the earthquake. In this paper, the causes of loosening and slackness of hanger cables during this inland earthquake are investigated through the response spectrum analysis, static elasto plastic finite displacement analysis by using the incremental seismic load and dynamic response analysis by using the actually recorded earthquake wave, of one of the two Nielsen-Lohse bridges.
