The GPL seismic cable bracing system is a set of cables strategically placed within a structure to provide additional lateral support. These cables are tensioned and anchored to key structural components, working together to absorb and distribute seismic forces. It is used as a bracing system for suspended nonstructural components, equipment and systems.
General Principles:
GPL bracing solution system must be designed by a qualified structural engineer to ensure that when installed
correctly they comply with the relevant standards.
- A pair of cables opposing each other are always required to brace a component, as loads are dynamic and cyclical.
- Cables should not touch any object along their length.
- Brace angles from the horizontal must not exceed 60°.
- Anchor points must be correctly qualified for the earthquake load demand, whether fixing to concrete, steel or timber.
- Anchor brackets must be loaded in line with the cable to prevent excessive prying of the anchors.
- The cables of a 4-way brace must directly oppose each other.
