1810.3.1.5.1 Helical Piles Seismic Requirements

Los Angeles Building Code > 18 Soils and Foundations > 1810 Deep Foundations > 1810.3 Design and Detailing > 1810.3.1 Design Conditions > 1810.3.1.5 Helical Piles > 1810.3.1.5.1 Helical Piles Seismic Requirements
JUMP TO FULL CODE CHAPTER

[OSHPD 2] For structures assigned to Seismic Design Category D, E or F, capacities of helical piles shall be determined in accordance with Section 1810.3.3 by at least two project specific pre-production tests for each soil profile, size and depth of helical pile. At least two percent of all production piles shall be proof tested to design ultimate strength determined by using load combinations in Section 1605.2.1.

Helical piles shall satisfy corrosion resistance requirements of ICC-ES AC 358. In addition, all helical pile materials that are subject to corrosion shall include at least 1/16" corrosion allowance.

Helical piles shall not be considered as carrying any horizontal loads.
