Summary

Conventional analysis of steel frames assumes either perfectly rigid or pinned connections. The rigidity of most connections behaves, in fact, somewhat between these two extremes. Therefore incorporating the effect of connection flexibility into the analysis and design procedure of the frame becomes necessary.

Buckling of a column is fundamental to the design of load bearing structures mainly when the analysis of such frames takes into account the effect of the connection flexibility.

The objective of this paper is to present a simplified approach for the evaluation of the elastic buckling load for steel frames with semi-rigid joints. To this end, a simple model that takes into account the effect of beam-to-column joint flexibility in the analysis of steel frames is proposed and a corresponding stiffness matrix element is presented. The model developed has been verified to be valid using an illustrative example found in the literature; numerical results are provided to illustrate the accuracy of the results.
