Table Run IDs
Specification of Uplift Restraint Systems
Table 1 — Allowable Loads for URS Runs

- Tabulated allowable load is the lowest allowable load of the threaded rod, coupler nut, take-up device and bearing plate components for each URS model.
Table 2 — Deflection Equations

- Tabulated deflection formulas account for rod elongation, wood bearing deformation and deflection of shrinkage compensating device.
- Where PD is the demand (or design) uplift load and L is the total length of the rod in inches between restraints (foundation level to take-up device).
Table 3 — Tabulated Deflection Tables Using RTUD

- Tabulated deflection values include rod elongation, wood bearing deformation and deflection of shrinkage compensating device.
- Noted values exceed the maximum allowable load for the URS run.
- Noted values exceed the maximum rod elongation of 0.18" specified in Section 3.2.1.1 of ICC-ES AC391.
- Where PD is the demand (or design) uplift load and L is the total length of the rod between restraints (foundation level to take-up device).
