Abstract : It is an object of the invention, therefore, to provide a prestressed concrete high energy absorbing pile having high elasticity. Another object of the invention is to provide a prestressed concrete high energy absorbing pile having partially prestressed reinforcing strands which allow substantial elasticity in bending and return of the pile to its original form following energy absorption. A further object of the invention is to provide a cost effective prestressed concrete pile for replacing conventional timber and steel fender piles. Other objects, advantages and novel features of the invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.
