PRACTICAL ANALYSIS OF THE ANCHORAGE ZONE PROBLEM IN PRESTRESSED BEAMS
THIS TWO-PART PAPER PRESENTS METHODS FOR /A/ THE DETERMINATION OF TRANSVERSE STRESSES AND /B/ THE PROPORTION- ING OF TRANSVERSE REINFORCEMENT IN THE ANCHORAGE ZONE OF PRESTRESSED CONCRETE BEAMS. THE METHODS PRESENTED ARE BASED ON A PHYSICAL ANALOG REPRESENTING THE END OF THE BEAM. PART 1 OF THE PAPER DESCRIBES THE BASIC FEATURES OF THE APPROACH, COMPARES THE RESULTS WITH OTHERS BASED ON THEORY AND EXPERI- MENT, DEVELOPS SIMPLE DESIGN PROCEDURES, AND CONCLUDES WITH NUMERICAL EXAMPLES. PART 2 DISCUSSES IN DETAIL THE DERIVATIONS ASSOCIATED WITH THE DEVELOPMENT OF THE PHYSICAL ANALOG. A CONSIDERABLE AMOUNT OF SIGNIFICANT WORK ON ANCHORAGE ZONE STRESSES HAS PRECEDED THIS PAPER. THE CONTRIBUTION OF THIS EFFORT IS THAT IT PROVIDES AN ANALYTICAL TOOL WHICH CAN BE USED IN DESIGN TO INVESTIGATE MANY DIFFERENT CONDITIONS WITHOUT THE NECESSITY OF LABORIOUS SOLUTIONS. /RRL/A/
