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
When cable trays have vertical drops of more than about 20 feet and flapping of the cables during an earthquake might cause pinching or cutting of the cables or impact with proximate fragile equipment,
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
As with cable restraints, floor- or roof-mounted electrical distribution support systems will normally involve a box frame that supports the system (single or multiple runs) with some kind of a trapeze bar.
This article discusses the importance of seismic resistance for cable trays, detailing when seismic braces are necessary, the factors that affect seismic resistance, and how to ensure your
Our team of experts can help you select the best cable tray series for your application, as well as designing your seismic bracing layout to ensure it meets applicable building codes and standards.
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
The seismic performance levels of cable tray systems are presented according to current seismic design codes. A performance-based optimum seismic design procedure for cable tray
The final results demonstrate the need to consider the effects of random variables in modeling assumption in seismic performance analyses of cable tray and can be further used in
The present invention relates to an earthquake-resistant cable tray and a duct, and more particularly, to a cable supporting structure for a cable bus and a bus duct, wire cable trays...
