Prestressed Concrete Cylinder Pile Analysis
Prestressed Concrete Cylinder Pile Analysis
(OP)
I'm looking for recommendations for a methodology to determine the structural and geotechnical capacity of existing spun-cast prestressed concrete cylinder piles. I need both the full-section (like-new) capacity and the capacity assuming longitudinal cracking in the pile.
Thanks.
Thanks.





RE: Prestressed Concrete Cylinder Pile Analysis
The geotechnical capacity is not affected by the presstressing of the pile. You can analyze it as a concrete square pile for geotechnical purposes.
For the structural capacity i would model it using non linear moment curvature (or EI vs moment) relations. That way you can account for the EI reduction for the cracked case.
RE: Prestressed Concrete Cylinder Pile Analysis
I assume your answer would still hold when the pile is in a pile bent configuration, i.e., significant exposed length above mudline.
