centroid of the tension reinforcement. Code Section 9.3.2 references Sections 10.3.3 and 10.3.4 where the strain values for tension control and compression control are defined. It should be note that the eccentricity ratios (e/h =M / P), sometimes included as diagonal lines on interaction diagrams, are not included in the interaction diagrams.

site.iugaza.edu.psShear stresses due to torsion create diagonal tension stresses that produce diagonal cracking. If the member is not adequately reinforced for torsion, a sudden brittle failure can occur. Since shear and moment usually develop simultaneously with torsion, a reasonable design should logically account for the interaction of these forces.
