Behavior of Batter Piles in Sand

Abstract

Effects of group interaction on behavior of small batter pile groups (3 x 3 and 4 x 4) were examined using the p-multiplier method proposed for the vertical piles. Average values of the p-multipliers appropriate for the small batter pile groups in sand were suggested. Investigations of various pile-to-pile cap connections for the prestressed concrete piles using full-scale static experimental results were performed. On the basis of analytical results, the degree of fixity for each pile-to-pile cap connection was proposed for being applied in the analysis and design of pile foundations.
