In conclusion, whether or not you need seismic braces for your cable trays depends on several factors, including local building codes, the importance
Industry Information SEISMIC BRACING OF A DISTRIBUTED CABLE TRAY SYSTEM
Traditional system for bracing cable trays using diagonal bracing extending up to the roof would have been impractical due to the extensive amount of cable trays, the lightweight framing of the roof, and
Industry Information 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.
Industry Information What are the seismic design considerations for cable trays?
The support spacing of the cable tray should be carefully determined based on the seismic design requirements. Closer support spacing can reduce the span of the
