Design and Installation Practices of Large Diameter Prestressed Concrete Piles

Abstract

This paper describes “The Recommendation for Design and Installation Practices of Large Diameter Spun Prestressed Concrete Piles”, proposed recently by the Concrete Committee of JSCE.One of the specific features prescribed in the recommendation is that the bearing capacity of PC piles should be decided depending upon the installation procedure to be used. In designing the pile size, a consideration should be given to the safety for seismic loads at the ultimate state. The N-Mu interaction curves for various PC piles of 0.3 to 1.2m diameter are also presented in the appendix.
