Abstract

The paper proposes the use of innovative devices devoted to the brittle collapse protection of welded steel sections, typically represented by the end beam cross-sections in framed structures. Reference is made to I-shaped cross-sections. At first, limiting to the case of plane stress, the relevant elastic domain is defined in the 𝑁𝑁, 𝑇𝑇, 𝑀𝑀 space; then a plane frame equipped with the proposed devices and subjected to seismic load condition is studied, ensuring that the generalized stresses at the welded sections be within the relevant elastic domain.
