Cable tray and conduit systems have an excellent earthquake performance record. This has been evidenced at over 70 power and industrial facilities in 14 past major earthquakes, and is reinforced by shake table test data and detailed analyses. Earthquakes and seismic events can cause severe damage to electrical infrastructure, including cable trays, leading to outages and even safety hazards. Seismic forces are generated by the movement of the Earth's crust during an earthquake. A method is developed for utilizing this data in defensible, simple seismic qualification criteria and configuration controls. During an earthquake, cable trays are exposed not only to gravity loads and normal service loads, but also to lateral movement, vertical acceleration, vibration, and building drift.
