STABILITY OF SLENDER PRESTRESSED CONCRETE PILING

A THEORETICAL ANALYSIS OF THE STRESSES AND DISPLACEMENTS WHICH MAY ARRIVE DURING THE INITIAL DRIVING STAGES OF PRESTRESSED CONCRETE PILING IS DEVELOPED. THE EQUATIONS OF MOTION INCLUDE THE EFFECTS OF LARGE DISPLACEMENTS AND NEGLECT THE EFFECTS OF ROTARY INERTIA AND SHEAR STROMS. THE BOUNDARY CONDITIONS AT THE TWO ENDS ARE SIMULATED WITH A LINEAR SPRING AT THE TIP, AND A FORCE-TIME RELATIONSHIP DEVELOPED FROM A RIGID MASS STRIKING THE END OF THE MEMBER. THE THEORETICAL SOLUTION WAS APPLIED TO MODELS WHICH WERE TESTED IN THE LABORATORY. COMPARISON OF THE MODEL TEST RESULTS AND THEORETICAL ANALYSES OF THE TESTED MEMBERS IS PRESENTED, ALONG WITH THE THEORETICAL ANALYSIS OF FULL-SIZED STRUCTURAL ELEMENTS. /AUTHOR/
