Influence of Joint Flexibility in the Seismic Performance of Moment Resisting Steel Frames
Semi-rigidity in beam-to-column joints of steel frames has increasingly attained attention during the last years. For braced frames it was repeatedly demonstrated that semi-rigid joints may lead to remarkable material savings compared to simple joints, mainly due to a beneficial moment distribution along the members and provision of higher rigidity to satisfy serviceability requirements. Such an evidence is still lacking for moment resisting frames, where joint flexibility may lead to higher lateral deformations and increased 2nd order effects.
