Cable Tray and Conduit System Seismic Evaluation Guidelines
Rigid-mounted conduit and cable trays are inherently very stable and subject to minimal seismic amplification. A detailed dead load design review of these systems provides ample margin for
Why do 150N/m Cable Trays Require Seismic Bracing?
Not all cable trays require seismic bracing. Smaller trays (e.g., 200mm) that contain only a few control or lightweight cables will typically have a total weight below 150N/m.
Appendix 3F Cable Trays and Cable Tray Supports
Cable ties are provided at spacing greater than 4 feet, thereby permitting cable movement within the trays. The damping ratio used for the cable tray system is dependent on the level of seismic input
