Key Technical Considerations
The load-bearing behavior of the system is highly specialized and fundamentally different from systems consisting solely of torque-controlled bonded anchors or solely of embedded channels
1. The external channel does not include anchor legs; the load from the catenary pole or equipment is first transferred to the external channel, redistributed through the channel, and then transferred to the torque-controlled bonded anchors
2. The external channel is not embedded in concrete; when subjected to shear forces perpendicular to the channel direction, the channel itself is not restrained by concrete, resulting in more demanding load conditions
3. The system failure modes are completely different, with multiple possible failure mechanisms, including anchor failure, concrete failure, slot failure, failure of the connection between channel and welded plate, failure of the welded anchor plate, and channel deformation failure
