PRELIMINARY INVESTIGATION OF HAULING STRESSES IN PRESTRESSED CONCRETE PILES

SINCE THE OVERALL STUDY INVOLVES TENSILE STRESSES DURING DRIVING OF PRESTRESSED CONCRETE PILES, AND THE AVAILABLE TENXILE CAPACITY MAY BE LOWERED IF THE PILE IS INITIALLY CRACKED DURING HANDLING OR HAULING, A LIMITED STUDY WAS INITIATED TO EXPLORE THE FEASIBILITY OF PREDICTING DYNAMIC TENSILE STRESSES INDUCED BY HAULING. A MATHEMATICAL MODEL WAS ESTABLISHED TO SIMULATE THE PILE AND HAUL TRAILER AND EXPERIMENTAL VALUES WERE OBTAINED FROM LIMITED TESTS WITH ONE PILE. FAIR CORRELATION OF EXPERIMENTAL AND ANALYTICAL DATA WAS ATTAINED INDICATING THAT FURTHER REFINEMENT AND MODIFICATION COULD PRODUCE AN EXACT MATHEMATICAL MODEL. /BPR/
