Abstrait:

The behaviour of steel frames is highly influenced by the way in which the beam-to-column connection is accomplished. For quite some time now, traditional design has regarded such connections as being either perfectly rigid or perfectly flexible (hinges), thus the calculation being developed starting from this assumption.

The paper aims to develop the theoretical concepts that are needed to include the characteristics of semi-rigid connections in the geometrical nonlinear approach. The analysis uses the finite element method and fundamental relationships are inferred by the separate and independent introduction of static, kinematic and constitutive conditions to be met.

Relevant numerical examples are given and discussed. Conclusions regarding the effect of semi- rigid connections upon the performance of steel frames are formulated in the final part of the article.
