Materials

Concrete Column: 10,000 (Nominal) psi pre-cast self consolidating concrete (SCC) with four (4) continuous vertical reinforcing bars of A706 weldable 60 ksi yield strength steel. Number 4 bars are used for the PC4600, PC6300, PC6400, and PC6600 while number 5 bars are used for the PC8300 and PC8400 models. Superplasticizers and polymer fiber reinforcement are added as well as other admixtures to increase freeze/thaw resistance, rust resistance, flexural and compressive strength as well as optimizing the hydration process.
Uplift Anchors: Galvanized, 36 ksi yield strength steel available in two sizes, PC20UA 2”x 2”x 8.5”x 0.134”; PC25UA 2”x 2”x 12”x 0.134”
Steel Bracket: A U-shaped ¼” ASTM A1018 Grade 40 steel bracket with 5/8” diameters holes for bolts, and 5/16” diameter holes for screws. The bracket uses ½” SAE J429 Grade 5 bolts with hex nuts torqued to 110 foot-pounds as well as 0.242”x3” structural screws or equal.

For biaxial bending: (mx / Mx) + (mz / Mz) ≤ 1
The tabulated values account for combined axial compression load and bending moment load. No reduction in axial compression loads and bending moment loads for combined axial compression bending moment is required.
For combined tension loads and bending moment loads: (t/T)+(m/M) ≤ 1
Length is measured from the top of the concrete to the bottom of the concrete.
For SI: 1 inch = 25.4 mm, 1 pound = 4.4482 N
