TORSION OF STRUCTURAL CONCRETE-UNIFORMLY PRESTRESSED RECTANGULAR MEMBERS WITHOUT WEB REINFORCEMENT

THE TORSIONAL STRENGTH OF A PRESTRESSED CONCRETE BEAM IS SHOWN TO BE EQUAL TO THAT OF A NON-PRESTRESSED BEAM MULTIPLIED BY A FACTOR ACCOUNTING FOR THE EFFECT OF PRESTRESS. THE EQUATION FOR TORSIONAL STRENGTH OF PRESTRESSED MEMBERS BECOMES A TORSIONAL STRENGTH OF NON- PRESTRESSED MEMBERS MULTIPLIED BY A FACTOR THAT ACCOUNTS FOR THE EFFECTS OF PRESTRESS. THIS PRESTRESS FACTOR IS IDENTICAL TO THAT DERIVED FROM THE CLASSICAL MAXIMUM TENSILE STRESS THEORY OF FAILURE. THE BENDING MECHANISM OF TORSIONAL FAILURE FOR PLAIN CONCRETE RECTANGULAR MEMBERS WAS EXTENDED TO UNIFORMLY PRESTRESSED RECTANGULAR MEMBERS AND WAS FOUND TO BE APPLICABLE. AN EQUATION FOR THE ULTIMATE TORSIONAL STRENGTH FOR PRESTRESSED CONCRETE MEMBERS WITHOUT WEB REINFORCEMENT WAS DERIVED. THE PRESTRESS FACTOR IS SUGGESTED FOR PRACTICAL DESIGN APPLICATIONS
