1810.6 Concrete-Filled Steel Pipe and Tube Piles

2010 Building Code of NY > 18 Soils and Foundations > 1810 Cast-In-Place Concrete Pile Foundations > 1810.6 Concrete-Filled Steel Pipe and Tube Piles
JUMP TO FULL CODE CHAPTER
Concrete-filled steel pipe and tube piles shall conform to the requirements of Sections 1810.6.1 through 1810.6.5.

1810.6.1 Materials

Steel pipe and tube sections used for piles shall conform to ASTM A 252 or ASTM A 283. Concrete shall conform to Section 1810.1.1. The maximum coarse aggregate size shall be 3/4 inch (19.1 mm).

1810.6.2 Allowable Stresses

The allowable design compressive stress in the concrete shall not exceed 33 percent of the 28-day specified compressive strength (f 'c). The allowable design compressive stress in the steel shall not exceed 35 percent of the minimum specified yield strength of the steel (Fy), provided Fy shall not be assumed greater than 36,000 psi (248 MPa) for computational purposes.

Exception: Where justified in accordance with Section 1808.2.10, the allowable stresses are permitted to be increased to 0.50 Fy.

1810.6.3 Minimum Dimensions

Piles shall have a nominal outside diameter of not less than 8 inches (203 mm) and a minimum wall thickness in accordance with Section 1809.3.4. For mandrel-driven pipe piles, the minimum wall thickness shall be 1/10 inch (2.5 mm).

1810.6.4 Reinforcement

Reinforcement steel shall conform to Section 1810.1.2. Reinforcement shall not be placed within 1 inch (25 mm) of the steel casing.

1810.6.4.1 Seismic Reinforcement

Where a structure is assigned to Seismic Design Category C, D, E or F in accordance with Section 1613, the following shall apply. Minimum reinforcement no less than 0.01 times the cross-sectional area of the pile concrete shall be provided in the top of the pile with a length equal to two times the required cap embedment anchorage into the pile cap, but not less than the tension development length of the reinforcement. The wall thickness of the steel pipe shall not be less than 3/16 inch (5 mm).

1810.6.5 Placing Concrete

The placement of concrete shall conform to Section 1810.1.3, but is permitted to be chuted directly into smooth-sided pipes and tubes without a centering funnel hopper.
