Cable tray seismic bracing is a support device that limits the displacement of electromechanical pipelines (such as water pipes, cable trays, and air ducts) and controls vibration during an earthquake, preventing pipelines from falling or being damaged. Technical overview of seismic cable tray design considerations including bracing splice reinforcement movement accommodation cable retention and support verification. High-seismicity projects place much greater demands on cable tray systems than ordinary installations. For over 60 years, the mechanical, electrical, and fire protection trades have relied on TOLCO seismic bracing solutions. Why is seismic bracing important? International Building Code. Seismic bracing, typically made of high-strength metal, is key component specifically designed to enhance the stability and safety of cable tray systems during earthquakes. By reinforcing the cable tray structure, it can effectively reduce the dynamic impact caused by earthquakes, ensuring that the. A number of shake table tests on portions of cable tray and conduit systems confirm these observations from past earthquakes and demonstrate that typical configurations perform well under repeated high- level seismic input test spectra on the order of 1.
