Prestressed Concrete Circular Hollow Pole/Pile Design Based on ACI 318-14 & AASHTO 17th



prestressed concrete circular hollow poles offer several advantages,Compared with normally reinforced concrete poles, Prestressed
poles are lighter and stronger, and they require
less reinforcing steel. The concrete is generally in compression,
so cracking is unlikely except from rough handling,
and the concrete that is used is usually of higher
strength so it can withstand the prestressing operation.
Due to the special manufacturing process, in which the
poles are spun at high speeds, they have a smoother surface
that is denser and less permeable. This lower permeability
in combination with the absence of cracks
prevents corrosion of reinforcement or prestressing
wire.
