Stability analysis of frames with flexible connection by transfer matrices

Record type: Article


The stability of flexibly connected unbraced frames is studied using a transfer matrix formulation which incorporates modified girder stiffness to account for both rotational connection deformation and the finite width of columns. In the case of linear modelling of connection flexibility, a direct iterative method yields the critical load. Empirical models for moment-rotation relations, developed from experimental data, are incorporated into a second numerical algorithm based on an incremental approach with the connection represented as a nonlinear rotational spring. The analyses and the computer code are systematically tested for accuracy and efficiency through comparison of their predictions with previously published results. Parametric studies give a clear indication of the effect of connection geometry and material behaviour on the critical load and sway deflection at working load.
