ANALYSIS OF FOUNDATION WITH WIDELY SPACED BATTER PILES

A THEORY FOR SOLVING THE DISPLACEMENT OF A TWO- DIMENSIONAL FOUNDTION WITH WIDELY SPACED BATTER PILES UNDER ANY ARBITRARY STATIC LOADING IS PRESENTED. THE THEORY IS CAPABLE OF DEALING WITH A HIGHLY NONLINEAR SOIL-PILE INTERACTION SYSTEM AS WELL AS THE NONLINEAR PILE MATERIAL. THE PILE IN THE FOUNDATION MAY POSSESS VARIABLE SECTIONAL PROPERTIES ALONG ITS AXIS AND MAY HAVE ANY DEGREE OF FIXITY TO THE PILE CAP. THE THEORY CONSISTS OF A NUMERICAL PROCEDURE FOR SEEKING THE EQUILIBRIUM OF THE APPLIED LOAD AND THE PILE REACTIONS USING FORMULATED FINITE DIFFERENCE METHODS TO COMPUTE THE PILE-TOP REACTIONS OF AN AXIALLY LOADED PILE AND A LATERALLY LOADED PILE. AN EXPERIMENT WAS CONDUCTED ON SMALL-SIZED STEEL PIPE PILES WHICH WERE TWO INCHES IN DIAMETER AND EMBEDDED EIGHT FEET IN A SUBMERGED, DENSE FINE SAND. A NUMBER OF SINGLE PILES WERE TESTED TO EXAMINE THE BEHAVIOR OF AN AXIALLY LOADED PILE AND A LATERALLY LOADED PILE. THEN, THE BEHAVIOR OF GROUPED PILE FOUNDATONS WITH FOUR PILES WERE COMPARED WITH ANALYTICAL PREDICTIONS WHICH WERE BASED ON INFORMATION ABOUT THE AXIAL BEHAVIOR OF A SINGLE PILE AND THE SOIL CRITERIA FOR A LATERALLY LOADED SINGLE PILE. GOOD AGREEMENT WAS OBTAINED BETWEEN THEORY AND EXPERIMENT. THE ANALYTICAL PROCEDURE WHICH IS PRESENTED CAN BE IMMEDIATLEY USEFUL IN COMPUTING THE BEHAVIOR OF A PILE SUPPORTED FOUNDATION UNDER INCLINED AND ECCENTRIC LOADING. /FHWA/
