ABSTRACT
Rational DSM-based design approaches for cruciform and angle columns must reflect the peculiarities of their behaviour, namely the fact that (i) both the F and P columns fail in interactive modes, combining minoraxis flexural and (i1) torsional (cruciforms) or (i2) major-axis flexural-torsional (angles) deformations, and that (ii) the above interaction is much stronger in the P angle columns, due to the effective centroid shift effects.
