316 Stainless Steel (or 2205 Stainless Steel) Tension Rods are tension only braces, with tensile strength data available but not dynamic performance data. At the Tawa Church, Wellington, a Tectonus Device (not supplied by Anzor) was used with Anzor Stainless Steel Tension Rods for seismic load demand.

Tension-only rod braces, whilst can be considered as a lateral load resisting system, cannot provide energy dissipation. Therefore the ductility factor as per code is 1.0-1.25. See the Tectonus Device.

By adding the Tectonus device, the ductility factor increases to 3.0-4.0 as such the seismic load demand could be reduced to about 1/3, providing significant cost savings for the gussets, welds, foundations, etc (in particular for retrofitting projects). As well as up front cost savings, there will be significant post event cost savings given no replacement is required, and the building would be fully resilient. It should be noted that the self-centering aspect of Tectonus device is a necessity for tension-only system, as other dampers with no re-storying capacity won't be applicable given the slender rods have no compression resistance to close the damper after its extension.
