Chance Technical Design Manual

BUILDING CODE COMPLIANCE PER ICC-ES ESR-2794 The following tables provide the nominal, LRFD design, and ASD allowable compression strengths of C1500121 foundation repair brackets, T-pipes, and Type SS5, SS150, RS2875.203, and RS2875.276 helical piles as evaluated per ICC-ES Acceptance Criteria AC358. These strengths are published in ICC-ES ESR 2794. The strengths listed are based on three different concrete foundation strengths and two different soils conditions—firm

and soft. The pile head is assumed to be fixed within the bracket assembly, and the piles are assumed to be braced. Per the International Building Code (IBC) 2006 Section 1808.2.9.2 & IBC 2021 Section 1810.2.1, piles can be considered fixed and laterally supported at 5 feet below the ground surface in firm soil and at 10 feet in soft soil.

Notes: For SI: 1 kip = 4.448 kN. 1 Refer to Section 4.1.3 of ICC-ES ESR-2794 for descriptions of fixed condition, pinned condition, soft soil, and firm soil. 2 Strength ratings are based on a design corrosion level of 50 years and presume the supported structure is braced in accordance with Section 1810.2.2 of the 2021 IBC (Section 1808.2.5 of the 2006 IBC). 3 Strength ratings apply to the specific bracket, T-pipe, and pile/anchor models listed. 4 See Section 4.1.2 of ICC-ES ESR-2794 for applicable limit states that must be evaluated by a registered design professional. 5 Refer to the specified compressive strength of concrete at 28 days.
