Lateral‐torsional buckling of a stiffened beam with semi‐rigid joints

Abstract: The paper presents an experiment and a numerical analysis of a steel beam subjected to three‐point bending. The beam was connected to short column stubs by bolted end plates. The joints were designed as semi‐rigid and their influence on the lateral‐torsional buckling resistance of the beam was evaluated. The cross‐sections of the beams and the columns were IPE 180 and HEB 140, respectively. The columns were 1 m long and were rigidly connected to the loading frame at their ends. The beams were 3.3 m long and we… Show more

“…All 9 specimens failed by lateral-torsional buckling as intended. The validation of CBFEM model including stiffeners was not available at the time the Eurosteel paper [15] was published. Loaddeformation curves of beams strengthened prior to load application (BU) and beams strengthened under load of 50 % load resistance (STR) are plotted in Figure 4 together with the load-deformation curve of CBFEM models with varying beam rotation, which is a parameter that was unfortunately not measured and was only estimated.…”
