Re: Upstate Job#1359
O'Neill Residence
Retrofit Holdown Alternate Anchorage
To Whom It May Concern:
Any T-1 or T-2 holdown shown on the holdown schedule for the above -referenced project can be
retrofit using Titen HD hardware rather than threaded rod and epoxy as originally specified. The
following hardware should be installed per the manufacturer's recommendations:
5/8" diameter X 5.5" (nominal) Titen HD
See supporting calculations attached. Should there be any questions or comments please contact
our office.
Sincerely,

11. Results
11. Interaction of Tensile and Shear Forces (Sec. D.7)?
Tension Factored Load, Nu. (lb) Design Strength, oNn (lb) Ratio Status
Steel 3144 19734 0.16 Pass
Concrete breakout 3144 3409 0.92 Pass (Governs)
Pullout 3144 5239 0.60 Pass
5/8" P1 Titen HD (THDB model), hnom:5.5" (140mm) meets the selected design criteria.
12. Warnings
- Per designer input, the tensile component of the strength -level earthquake force applied to anchors does not exceed 20 percent of the total
factored anchor tensile force associated with the same load combination. Therefore the ductility requirements of ACI 318 17.2.3.4.2 for tension
need not be satisfied — designer to verify.
- Per designer input, the shear component of the strength -level earthquake force applied to anchors does not exceed 20 percent of the total
factored anchor shear force associated with the same load combination. Therefore the ductility requirements of ACI 318 17.2.3.5.2 for shear
need not be satisfied — designer to verify.
- Designer must exercise own judgement to determine if this design is suitable.
- Refer to manufacturer's product literature for hole cleaning and installation instructions.
