| 摘要： | The overall objective of this project was to characterize the axial capacity of typical CIP piles as a means to evaluate which design approach is more representative of the piles used by WisDOT in bridge and retaining wall structures. In addressing this issue, the research would quantify the effect of composite action in pile capacity. In order to do so, two primary factors must be considered: the actual compressive strength of the in-place concrete, which free-falls into the steel shells as it is poured; and the composite action between the concrete core and the steel shell. |
