The lateral instability of a simply supported deep beam subjected to a concentrated load at its centroid

摘要

Although the theoretical solution to the problem of thelateral buckling of a simply supported deep beam subjected to aconcentrated load at its centroid has existed for many yearsexperimental investigation to substantiate the theory has notbeen entirely definitive. Bromley and Robinson^ in fact, wereunable to achieve agreement between theory and experiment. Trayerand March attempted to analyze this apparent discrepancy and obtainedsatisfactory agreement with theory in their own tests.Further experimental verification is shown in a paper by Dumontand Hill.
