Abstract: Based on the familiar skew‐bending model, strength equations are developed to predict the torsional strength of prestressed concrete beams containing a small circular transverse opening and subjected to torsion. Test results ...

Abstract: Strength equations based on the skew‐bending model have been developed to predict the torsional strength of prestressed concrete beams containing a circular transverse opening and subjected to combined torsion and bending. ...

Abstract: Test results of 17 axially prestressed concrete beams without stirrups and containing a transverse circular opening are presented. Mainly, beams having two different opening diameters were subjected to various combinations ...

Abstract: Fourteen prestressed high-strength concrete beams were tested to study their torsional behavior. The major variables were the concrete compressive strength, the aspect ratio of the beam cross section, the prestressing ...
