DESIGN OF PILES IN PERMAFROST UNDER COMBINED LATERAL AND AXIAL LOAD

Piles in permafrost subjected to horizontal forces, axial forces, and moments may reach their ultimate capacity either through attaining the ultimate strength of the cross section or through inelastic instability. Empirical interaction equations are used in design to provide uniform strength against failure by either modes. The stability interaction equation attempts to assess the overall capacity of the member while the strength interaction equation checks the local moment capacity of the cross section. It is noted that a simplification which transforms the partially embedded pile to an equivalent cantilever fixed at some depth, is no longer required. The overall stability of the pile-soil system can now be performed in accordance with established codes and criteria.
