Home / Seismic Support for Multi-layer Cable Trays
This study aims to develop a simple yet efficient performance-based design optimization methodology for cable tray systems in building structures.
Cable trays are light equipment components. They consist of steel ladder type cable trays and a support system. In case of horizontal cable trays, the trays are supported by cantilevers
