The seismic performance of a cable tray system depends just as much on the building connection as on the tray itself. Every hanger, trapeze, beam clamp, concrete insert, and post-installed anchor should be reviewed for the seismic forces expected at that attachment. A coordinated seismic bracing system uses strut channels, clamps, connectors, anchors, and tray interfaces as one load path from the cable tray to the building structure. Why does seismic cable tray bracing deserve more attention than a simple code check? Seismic cable tray bracing. Hongfeng Electric supplies cable tray, cable ladder, strut channel, brackets, splice components, covers, and related support accessories for coordinated project packages. 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. If these. An innovative bracing system was designed to provide lateral bracing for the cable tray system. Recommendations are made for improvements in the design procedures for seismic bracing of. This article will explore the importance of seismic resistance in cable trays, discuss when seismic braces are necessary, and help you understand how to make informed decisions for your installation.
