WebDec 15, 2024 · Another example of an alternative use for helical piles is a sign pylon foundation we recently built. For this foundation, we installed opposing pairs of batter piles at a 7.5-degree angle from the vertical to anchor the sign’s steel framework. That orientation—rather than a completely vertical one—will provide better resistance to uplift ... Web1. Axial Loads. An axial load may be either compressive (downward) or tensile (uplift). When it is compressive, deep foundations resist the load using friction resistance and toe bearing resistance, as shown in Fig. 1. However, when the load is tensile, the resistance is caused by side friction and the weight of the foundation as shown in Fig ...
WebNov 9, 2024 · The helical piles can effectively resist lateral forces and are exclusively controlled by shaft diameter. The lack of detailed research in combined loading is observed, viz., lateral—compression, lateral—uplift in that lateral load as static or dynamic deters the validity of the design. Webcapacities of helical piles. Helical piles with axial capacities in excess of 3 MN are now in use. However, very little information is available on their lateral behaviour since helical …

When the pile cap can be considered for resisting the lateral load, the longer side of the strip-shape pile cap can provide much more lateral resistance than shorter side and will not control the design. As indicated
