This study investigates the behaviour of a plate girder web subjected to repeated loading into the post-buckling range, by means of the analysis of experimental data obtained from the testing of one large-scale plate girder. The test girder was designed in accordance with BS 153: parts 3B & 4: 1972 using the maximum allowable web depth to web thickness ratio of 200, for webs stiffened vertically only, and was tested as a simply supported unit under a mid-span point load. Results are presented for repeated loading up to, and in excess of, the design fatigue life including overload of the girder, and final static tests up to the ultimate load capacity, with comparisons being made to current theory. The girder was found to have a low factor of safety against the formation of permanent buckles at working load, and a low factor of safety against collapse, but the behaviour observed under repeated loading was altogether satisfactory with no deficiencies in performance apparent prior to the final static tests to ultimate load.
