  • Abstract:
    Sign structures in Wisconsin are typically supported by drilled shaft foundations or spread

    footing foundations. However, when the soil conditions are not suitable to be supported on

    drilled shafts or spread footings, a group of piles could support the foundation. Large sign

    structures are subject to large lateral wind loads, which result in large lateral forces and overturning

    moments. These lateral forces and overturning moments produce both uplift loads and downward

    loads on the pile foundation. However, published methods for designing driven pile groups only

    address groups subjected either to compression or uplift, not both simultaneously. This research

    project investigated the behavior of the group of piles under both compression and uplift loads.
