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

Abstract

Although the theoretical solution to the problem of the lateral buckling of a simply supported deep beam subjected to a concentrated load at its centroid has existed for many years experimental investigation to substantiate the theory has not been entirely definitive. Bromley and Robinson^ in fact, were unable to achieve agreement between theory and experiment. Trayer and March attempted to analyze this apparent discrepancy and obtained satisfactory agreement with theory in their own tests. Further experimental verification is shown in a paper by Dumont and Hill.
