Abstract

In order to subdivide members into ductility classes is important to know the slenderness factor “ s ”, which can be defined as the ratio between critical tension that brings local instability of the compressed flange or the flexural-torsional instability and the yield tension. The current paper deals with the redefinition of coefficients in the expression of the over-strength factor “ s ” proposed by the new seismic Italian code OPCM 3274 for hot rolled and welded double-T sections and with the introduction of a new expression of the same parameter for other members with different shape like rectangular, square and circular hollow sections and slender C sections.
