DESIGN PROCEDURE COMPARED TO FULL SCALE TESTS OF DRILLED SHAFT FOOTINGS

Abstract

A THEORY WHICH WILL PREDICT THE ULTIMATE RESISTANCE OF A DRILLED SHAFT FOOTING TO OVERTURNING LOADS WAS PRESENTED IN RESEARCH REPORT 105-1 AND WAS CORRELATED WITH MODEL TESTS REPORTED IN RESEARCH REPORT 105-2. IN THIS PAPER THE RESULTS OF FULL-SCALE TESTS ON DRILLED SHAFT FOOTINGS ARE PRESENTED AND COMPARED TO A TENTATIVE DESIGN PROCEDURE BASED ON THE PREVIOUSLY PUBLISHED THEORY. DESIGN CURVES ARE GIVEN AS A PART OF THE DESIGN PROCEDURE, WHICH RESULT IN EASY APPLICATION OF THE THEORY. ALSO INCLUDED IS AN EXAMPLE PROBLEM AND A SECTION ON ESTIMATING THE SOIL PARAMETERS NECESSARY FOR THE DESIGN OF THESE FOOTINGS. THE RESULTS OF THIS STUDY HAVE NOW REACHED THE STAGE WHERE FULL IMPLEMENTATION CAN BE ACHIEVED. /AUTHOR/
