Performance of Pile Supported Sign Structures. Final Report.

摘要

Sign structures in Wisconsin are often founded on groups of driven piles. Published methods for design of driven pil egroups subjected to axial compression or uplift are readily available. However, overturning loads are predominant for sign foundations, where some piles are subjected to compression and others uplift. Currently available design methods do not address this condition. A lateral load test of two four-pile groups was therefore conducted to evaluate load transfer among the piles, especially as the groups approach failure, and evaluate potential design implications.
