TORSION DESIGN OF PRESTRESSED CONCRETE

THIS PAPER PROPOSES AN EXTENSION OF THE ACI DESIGN PROCEDURES TO COVER TORSION IN PRESTRESSED CONCRETE. THE BASIC APPROACH CONSISTS OF DETERMINING THE CONCRETE CONTRIBUTION TO THE ULTIMATE STRENGTH OF A MEMBER AND THEN PROPORTIONING REINFORCEMENT FOR THE REMAINING PORTION OF THE REQUIRED ULTIMATE STRENGTH. FORMULAS FOR THE NOMINAL TORSIONAL STRESS AND THE BASIC EQUATION FOR TORSIONAL STRENGTH OF REINFORCED MEMBERS ARE PRESENTED, FOLLOWED BY A DESCUSSION OF THE TORSION-SHEAR INTERACTION RELATION, TAKING INTO ACCOUNT THE EFFECT OF THE PRESTRESSING FORCE. REQUIREMENTS FOR BOTH WEB AND LONGITUDINAL REINFORCEMENTS FOR TORSION ARE EXPLAINED. /AUTHOR/
