Abstract
By employing large scale shaking table, ultimate strength test was conducted for cable tray used in nuclear power plants. Test results revealed follows; (1)under S2 earthquake, damping ratio was so large, more than 30% due to rubbing phenomena of cables, that large response was not caused and support strains were under elastic limits (2)support had strength to sustain cable trays when support strains were 20 time larger than elastic strains. This report describes the results of shaking table test.
